It is well-tested and includes robust support for custom token lengths, authentication windows, hash algorithms like SHA256 and SHA512, and other features, and includes helpers like a secret key generator. Speakeasy implements one-time passcode generators as standardized by the [Initiative for Open Authentication (OATH)][oath]. The HMAC-Based One-Time Password (HOTP) algorithm defined by [RFC 4226][rfc4226] and the Time-Based One-time Password (TOTP) algorithm defined in [RFC 6238][rfc6238] are supported. This project incorporates code from [passcode][], originally a fork of Speakeasy, and [notp][]. ## Install ```sh npm install --save speakeasy ``` ## Demo This demo uses the `generateSecret` method of Speakeasy to generate a secret key, displays a Google Authenticator–compatible QR code which you can scan into your phone's two-factor app, and shows the token, which you can verify with your phone. Includes sample code. https://sedemo-mktb.rhcloud.com/

## Two-Factor Usage Let's say you have a user that wants to enable two-factor authentication, and you intend to do two-factor authentication using an app like Google Authenticator, Duo Security, Authy, etc. This is a three-step process: 1. Generate a secret 2. Show a QR code for the user to scan in 3. Authenticate the token for the first time ### Generating a key Use Speakeasy's key generator to get a key. ```js var secret = speakeasy.generateSecret(); // Returns an object with secret.ascii, secret.hex, and secret.base32. // Also returns secret.otpauth_url, which we'll use later. ``` This will generate a secret key of length 32, which will be the secret key for the user. Now, we want to make sure that this secret works by validating the token that the user gets from it for the first time. In other words, we don't want to set this as the user's secret key just yet – we first want to verify their token for the first time. We need to persist the secret so that we can use it for token validation later. So, store one of the encodings for the secret, preferably `secret.base32`, somewhere temporary, since we'll use that in the future to authenticate the user's first token. ```js // Example for storing the secret key somewhere (varies by implementation): user.two_factor_temp_secret = secret.base32; ``` ### Displaying a QR code Next, we'll want to display a QR code to the user so they can scan in the secret into their app. Google Authenticator and similar apps take in a QR code that holds a URL with the protocol `otpauth://`, which you get automatically from `secret.otpauth_url`. Use a QR code module to generate a QR code that stores the data in `secret.otpauth_url`, and then display the QR code to the user. This is one simple way to do it, which generates a PNG data URL which you can put into an `` tag on a webpage: ```js // Use the node-qrcode package // npm install --save node-qrcode var QRCode = require('qrcode'); // Get the data URL of the authenticator URL QRCode.toDataURL(secret.otpauth_url, function(err, data_url) { console.log(data_url); // Display this data URL to the user in an tag // Example: write('

'); }); ``` Ask the user to scan this QR code into their authenticator app. ### Verifying the token Finally, we want to make sure that the token on the server side and the token on the client side match. The best practice is to do a token check before fully enabling two-factor authenticaton for the user. This code applies to the first and subsequent token checks. After the user scans the QR code, ask the user to enter in the token that they see in their app. Then, verify it against the secret. ```js // Let's say the user says that the token they have is 132890 var userToken = '132890'; // Let's say we stored the user's temporary secret in a user object like above: // (This is specific to your implementation) var base32secret = user.two_factor_temp_secret; ``` ```js // Use verify() to check the token against the secret var verified = speakeasy.totp.verify({ secret: base32secret, encoding: 'base32', token: userToken }); ``` `verified` will be true if the token is successfully verified, false if not. If successfully verified, you can now save the secret to the user's account and use the same process above whenever you need to use two-factor to authenticate the user, like during login. ```js // Example for saving user's token (varies by implementation): user.two_factor_secret = user.two_factor_temp_secret; user.two_factor_enabled = true ``` Now you're done implementing two-factor authentication! ## General Usage ```js var speakeasy = require("speakeasy"); ``` #### Generating a key ```js // Generate a secret key. var secret = speakeasy.generateSecret({length: 20}); // Access using secret.ascii, secret.hex, or secret.base32. ``` #### Getting a time-based token for the current time ```js // Generate a time-based token based on the base-32 key. // HOTP (counter-based tokens) can also be used if `totp` is replaced by // `hotp` (i.e. speakeasy.hotp()) and a `counter` is given in the options. var token = speakeasy.totp({ secret: secret.base32, encoding: 'base32' }); // Returns token for the secret at the current time // Compare this to user input ``` #### Verifying a token ```js // Verify a given token var tokenValidates = speakeasy.totp.verify({ secret: secret.base32, encoding: 'base32', token: '123456', window: 6 }); // Returns true if the token matches ``` #### Verifying a token and calculating a delta A TOTP is incremented every `step` time-step seconds. By default, the time-step is 30 seconds. You may change the time-step using the `step` option, with units in seconds. ```js // Verify a given token is within 3 time-steps (+/- 2 minutes) from the server // time-step. var tokenDelta = speakeasy.totp.verifyDelta({ secret: secret.base32, encoding: 'base32', token: '123456', window: 2, step: 60 }); // Returns {delta: 0} where the delta is the time step difference // between the given token and the current time ``` #### Getting a time-based token for a custom time ```js var token = speakeasy.totp({ secret: secret.base32, encoding: 'base32', time: 1453667708 // specified in seconds }); ``` #### Calculating a counter-based token ```js // Get a counter-based token var token = speakeasy.hotp({ secret: secret.base32, encoding: 'base32', counter: 123 }); // Verify a counter-based token var tokenValidates = speakeasy.hotp.verify({ secret: secret.base32, encoding: 'base32', token: '123456', counter: 123 }); ``` #### Using other encodings The default encoding (when `encoding` is not specified) is `ascii`. ```js // Specifying an ASCII token for TOTP // (encoding is 'ascii' by default) var token = speakeasy.totp({ secret: secret.ascii }); ``` ```js // Specifying a hex token for TOTP var token = speakeasy.totp({ secret: secret.hex, encoding: 'hex' }); ``` #### Using other hash algorithms The default hash algorithm is SHA1. ```js // Specifying SHA256 var token = speakeasy.totp({ secret: secret.ascii, algorithm: 'sha256' }); ``` ```js // Specifying SHA512 var token = speakeasy.totp({ secret: secret.ascii, algorithm: 'sha512' }); ``` #### Getting an otpauth:// URL and QR code for non-SHA1 hash algorithms ```js // Generate a secret, if needed var secret = speakeasy.generateSecret(); // By default, generateSecret() returns an otpauth_url for SHA1 // Use otpauthURL() to get a custom authentication URL for SHA512 var url = speakeasy.otpauthURL({ secret: secret.ascii, label: 'Name of Secret', algorithm: 'sha512' }); // Pass URL into a QR code generator ``` #### Specifying a window for verifying HOTP and TOTP Verify a HOTP token with counter value 42 and a window of 10. HOTP has a one-sided window, so this will check counter values from 42 to 52, inclusive, and return a `{ delta: n }` where `n` is the difference between the given counter value and the counter position at which the token was found, or `undefined` if it was not found within the window. See the `hotp․verifyDelta(options)` documentation for more info. ```js var token = speakeasy.hotp.verifyDelta({ secret: secret.ascii, counter: 42, token: '123456', window: 10 }); ``` How this works: ```js // Set ASCII secret var secret = 'rNONHRni6BAk7y2TiKrv'; // Get HOTP counter token at counter = 42 var counter42 = speakeasy.hotp({ secret: secret, counter: 42 }); // => '566646' // Get HOTP counter token at counter = 45 var counter45 = speakeasy.hotp({ secret: secret, counter: 45 }); // => '323238' // Verify the secret at counter 42 with the actual value and a window of 10 // This will check all counter values from 42 to 52, inclusive speakeasy.hotp.verifyDelta({ secret: secret, counter: 42, token: counter42, window: 10 }); // => { delta: 0 } because the given token at counter 42 is 0 steps away from the given counter 42 // Verify the secret at counter 45, but give a counter of 42 and a window of 10 // This will check all counter values from 42 to 52, inclusive speakeasy.hotp.verifyDelta({ secret: secret, counter: 42, token: counter45, window: 10 }); // => { delta: 3 } because the given token at counter 45 is 0 steps away from given counter 42 // Not in window: specify a window of 1, which only tests counters 42 and 43, not 45 speakeasy.hotp.verifyDelta({ secret: secret, counter: 42, token: counter45, window: 1 }); // => undefined // Shortcut to use verify() to simply return whether it is verified as within the window speakeasy.hotp.verify({ secret: secret, counter: 42, token: counter45, window: 10 }); // => true // Not in window: specify a window of 1, which only tests counters 42 and 43, not 45 speakeasy.hotp.verify({ secret: secret, counter: 42, token: counter45, window: 1 }); // => false ``` Verify a TOTP token at the current time with a window of 2. Since the default time step is 30 seconds, and TOTP has a two-sided window, this will check tokens between [current time minus two tokens before] and [current time plus two tokens after]. In other words, with a time step of 30 seconds, it will check the token at the current time, plus the tokens at the current time minus 30 seconds, minus 60 seconds, plus 30 seconds, and plus 60 seconds – basically, it will check tokens between a minute ago and a minute from now. It will return a `{ delta: n }` where `n` is the difference between the current time step and the counter position at which the token was found, or `undefined` if it was not found within the window. See the `totp․verifyDelta(options)` documentation for more info. ```js var verified = speakeasy.totp.verifyDelta({ secret: secret.ascii, token: '123456', window: 2 }); ``` The mechanics of TOTP windows are the same as for HOTP, as shown above, just with two-sided windows, meaning that the `delta` value can be negative if the token is found before the given time or counter. ```js var secret = 'rNONHRni6BAk7y2TiKrv'; // By way of example, we will force TOTP to return tokens at time 1453853945 and // at time 1453854005 (60 seconds ahead, or 2 steps ahead) var token1 = speakeasy.totp({ secret: secret, time: 1453853945 }); // 625175 var token3 = speakeasy.totp({ secret: secret, time: 1453854005 }); // 222636 // We can check the time at token 3, 1453853975, with token 1, but use a window of 2 // With a time step of 30 seconds, this will check all tokens from 60 seconds // before the time to 60 seconds after the time speakeasy.totp.verifyDelta({ secret: secret, token: token1, window: 2, time: 1453854005 }); // => { delta: -2 } // This signifies that the given token, token1, is -2 steps away from // the given time, which means that it is the token for the value at // (-2 * time step) = (-2 * 30 seconds) = 60 seconds ago. ``` As shown previously, you can also change `verifyDelta()` to `verify()` to simply return a boolean if the given token is within the given window. ## Documentation Full API documentation (in JSDoc format) is available below and at http://speakeasyjs.github.io/speakeasy/

By default, it verifies the token at the given counter value, with no leeway (no look-ahead or look-behind). A token validated at the current counter value will have a delta of 0. You can specify a window to add more leeway to the verification process. Setting the window param will check for the token at the given counter value as well as `window` tokens ahead (one-sided window). See param for more info. `verifyDelta()` will return the delta between the counter value of the token and the given counter value. For example, if given a counter 5 and a window 10, `verifyDelta()` will look at tokens from 5 to 15, inclusive. If it finds it at counter position 7, it will return `{ delta: 2 }`. **Kind**: function **Returns**: Object - On success, returns an object with the counter difference between the client and the server as the `delta` property (i.e. `{ delta: 0 }`). | Param | Type | Default | Description | | --- | --- | --- | --- | | options | Object | | | | options.secret | String | | Shared secret key | | options.token | String | | Passcode to validate | | options.counter | Integer | | Counter value.

Specify the key, and receive the one-time password for that time as a string. By default, it uses the current time and a time step of 30 seconds, so there is a new token every 30 seconds. You may override the time step and epoch for custom timing. You can also specify a token length, as well as the encoding (ASCII, hexadecimal, or base32) and the hashing algorithm to use (SHA1, SHA256, SHA512). Under the hood, TOTP calculates the counter value by finding how many time steps have passed since the epoch, and calls HOTP with that counter value. **Kind**: function **Returns**: String - The one-time passcode. | Param | Type | Default | Description | | --- | --- | --- | --- | | options | Object | | | | options.secret | String | | Shared secret key | | [options.time] | Integer | | Time in seconds with which to calculate counter value.

The number of digits for the one-time passcode. | ### totp․verifyDelta(options) ⇒ Object Verify a time-based one-time token against the secret and return the delta. By default, it verifies the token at the current time window, with no leeway (no look-ahead or look-behind). A token validated at the current time window will have a delta of 0. You can specify a window to add more leeway to the verification process. Setting the window param will check for the token at the given counter value as well as `window` tokens ahead and `window` tokens behind (two-sided window). See param for more info. `verifyDelta()` will return the delta between the counter value of the token and the given counter value. For example, if given a time at counter 1000 and a window of 5, `verifyDelta()` will look at tokens from 995 to 1005, inclusive. In other words, if the time-step is 30 seconds, it will look at tokens from 2.5 minutes ago to 2.5 minutes in the future, inclusive. If it finds it at counter position 1002, it will return `{ delta: 2 }`. If it finds it at counter position 997, it will return `{ delta: -3 }`. **Kind**: function **Returns**: Object - On success, returns an object with the time step difference between the client and the server as the `delta` property (e.g. `{ delta: 0 }`). | Param | Type | Default | Description | | --- | --- | --- | --- | | options | Object | | | | options.secret | String | | Shared secret key | | options.token | String | | Passcode to validate | | [options.time] | Integer | | Time in seconds with which to calculate counter value.
