Auto-generate TOTP tokens

Can automatically generate and fill out login-fields for TOTP (authenticator app) tokens.

Warning

Use at own risk. It significantly reduces the security of 2FA by effectively reducing it to 1-factor.

Requirements

For use: Extension Greasemonkey for Chrome or Tampermonkey for Firefox

For setting up: Nodejs

How to setup

1. Pull project
2. Go to service you want to add this to, add new authenticator. When it gives you the step to scan a QR-code, say you cannot scan it. You should then get a secret a roughly 16 character random string.
3. Copy the secret.
4. In the code, go to ./src/totp-config.js, insert the secret instead of ENTER TOTP SECRET HERE.
5. In command line, run: npm install, then npm run build
6. Go to ./dist/totp-autofill.user.js
7. If the authenticator setup asks for a token to verify, paste the contents of ./dist/totp-autofill.user.js into a javascript console to get a token.
8. On the login page you want this to work for, add a new grease- or tampermonkey userscript, insert contents of ./dist/totp-autofill.user.js.
9. In the top of the script in Grease- or Tampermonkey, replace // @match http*://example.com/ with // @match [whatever url you're currently on]
