-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.

-      agreed to in writing, Licensor provides the Work (and each

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

+There are a number of apps that various websites use to give you 6-digit codes to increase security when you log in:
+
+* [Authy](https://www.authy.com/personal/) [iPhone](https://itunes.apple.com/us/app/authy/id494168017?mt=8) | [Android](https://play.google.com/store/apps/details?id=com.authy.authy&hl=en) | [Chrome](https://chrome.google.com/webstore/detail/authy/gaedmjdfmmahhbjefcbgaolhhanlaolb?hl=en) | [Linux](https://www.authy.com/personal/) | [OS X](https://www.authy.com/personal/) | [BlackBerry](https://appworld.blackberry.com/webstore/content/38831914/?countrycode=US&lang=en)

+* GAuth [FxOS](https://marketplace.firefox.com/app/gauth/)
+
+There are many [Services that Support MFA](http://lifehacker.com/5938565/heres-everywhere-you-should-enable-two-factor-authentication-right-now),
+including Google, Microsoft, Facebook, and Digital Ocean for starters.
+
+This module uses [`botp`](https://git.coolaj86.com/coolaj86/botp.js) which implements `TOTP` [(RFC 6238)](https://www.ietf.org/rfc/rfc6238.txt)
+(the *Authenticator* standard), which is based on `HOTP` [(RFC 4226)](https://www.ietf.org/rfc/rfc4226.txt)
+to provide codes that are exactly compatible with all other *Authenticator* apps and services that use them.
+
+Demo

+
+Usage
+=====
+
+```bash
+bower install authenticator --save

+
+```javascript
+'use strict';
+
+var authenticator = window.Authenticator;
+
+authenticator.generateKey().then(function (formattedKey) {
+  // "acqo ua72 d3yf a4e5 uorx ztkh j2xl 3wiz"
+
+  authenticator.generateTotpUri(formattedKey, "john.doe@email.com", "ACME Co", 'SHA1', 6, 30);
+  //
+  // otpauth://totp/ACME%20Co:john.doe@email.com?secret=ACQOUA72D3YFA4E5UORXZTKHJ2XL3WIZ&issuer=ACME%20Co&algorithm=SHA1&digits=6&period=30
+
+
+  authenticator.generateToken(formattedKey).then(function (formattedToken) {
+    // "957 124"
+
+    authenticator.verifyToken(formattedKey, formattedToken).then(function (result) {
+      // { delta: 0 }
+    });
+
+    authenticator.verifyToken(formattedKey, '000 000').then(function (result) {
+      // null

+  });
+});

+
+### Browsers that support WebCrypto
+
+In total there are only a few hundred lines of uncompressed code here.
+
+Each file is very small.

+
+TODO: I'd love some help pruning the important bits out of the forge code.
+Just using an alternate CPRNG would be very helpful in trimming the fat.
+
+## API
+
+### generateKey()
+
+generates a 32-character (160-bit) base32 key
+
+### generateToken(formattedKey)
+
+generates a 6-digit (20-bit) decimal time-based token
+
+### verifyToken(formattedKey, formattedToken)
+
+validates a time-based token within a +/- 30 second (90 seconds) window
+
+returns `null` on failure or an object such as `{ delta: 0 }` on success
+
+### generateTotpUri(formattedKey, accountName, issuer, algorithm, digits, period)
+
+generates an `OTPAUTH://` scheme URI for QR Code generation.
+
+**OTPAuth Scheme**
+
+* <https://github.com/google/google-authenticator/wiki/Key-Uri-Format>
+* `otpauth://totp/<<ISSUER>>:<<ACCOUNT_NAME>>?secret=<<BASE32_KEY>>&issuer=<<ISSUER>>`
+* `otpauth://totp/<<ISSUER>>:<<ACCOUNT_NAME>>?secret=<<BASE32_KEY>>&issuer=<<ISSUER>>&algorithm=<<ALGO>>&digits=<<INT>>&period=<<SECONDS>>`
+
+Note that `ISSUER` is specified twice for backwards / forwards compatibility.
+
+QR Code
+-------
+
+See <https://davidshimjs.github.io/qrcodejs/> and <https://github.com/soldair/node-qrcode>.
+
+![](http://cdn9.howtogeek.com/wp-content/uploads/2014/10/sshot-7-22.png)
+
+Example use with `qrcode.js` in the browser:
+
+```javascript
+'use strict';
+
+var el = document.querySelector('.js-qrcode-canvas');
+var link = "otpauth://totp/{{NAME}}?secret={{KEY}}";
+var name = "Your Service";
+                                              // remove spaces, hyphens, equals, whatever
+var key = "acqo ua72 d3yf a4e5 uorx ztkh j2xl 3wiz".replace(/\W/g, '').toLowerCase();
+
+var qr = new QRCode(el, {
+  text: link.replace(/{{NAME}}/g, name).replace(/{{KEY}}/g, key)
+});
+```
+
+Formatting
+----------
+
+All non-alphanumeric characters are ignored, so you could just as well use hyphens
+or periods or whatever suites your use case.
+
+These are just as valid:
+
+* "acqo ua72 d3yf a4e5 - uorx ztkh j2xl 3wiz"
+* "98.24.63"
+
+0, 1, 8, and 9 also not used (so that base32).
+To further avoid confusion with O, o, L, l, I, B, and g
+you may wish to display lowercase instead of uppercase.
+
+TODO: should this library replace 0 with o, 1 with l (or I?), 8 with b, 9 with g, and so on?
+
+90-second Window
+----------------
+
+The window is set to +/- 1, meaning each token is valid for a total of 90 seconds
+(-30 seconds, +0 seconds, and +30 seconds)
+to account for time drift (which should be very rare for mobile devices)
+and humans who are handicapped or otherwise struggle with quick fine motor skills (like my grandma).
+
+
+Install WebApp
+--------------
+
+```bash
+git clone --depth 1 https://git.coolaj86.com/coolaj86/browser-authenticator.js.git
