2FA Autofill

Stores your 2FA (TOTP) secrets in an encrypted vault and fills verification codes on the sites you choose.

2FA Autofill fills in your two-factor authentication (2FA) codes for you. When a website asks for a verification code, the code is entered automatically or with one click, so you don't need to reach for your phone. FEATURES • Fills verification codes automatically on the websites you choose • A small button next to code fields lets you pick an account with one click • Works with single code boxes and "one box per digit" layouts • Keyboard shortcut: Alt+Shift+O fills the code on the current page • Import your accounts from Google Authenticator: use "Transfer accounts → Export accounts", then hold the QR code up to your webcam or upload a photo • Add accounts with a setup key or an otpauth:// link • Save the website, username and email with each account • Live codes with a countdown, plus one-click copy • Supports 6 or 8 digits and SHA-1, SHA-256 and SHA-512 SECURITY AND PRIVACY • Your secret keys are encrypted with AES-256 using a key derived from your master password (PBKDF2, 600,000 rounds) • Everything is stored only in your browser. Nothing is sent to any server and there is no account to create • The vault locks automatically after a period of inactivity and whenever Chrome closes • Websites never see your secret keys, only the current code, and only on the websites you listed for that account • Encrypted backup and restore Tip: keep your websites' backup/recovery codes somewhere safe. If you forget your master password, the vault cannot be recovered.
