OTP Deck

Organize and copy your two-factor authentication codes.

OTP Deck is a two-factor authenticator for desktop Chrome. Pin your favorite time-based one-time passwords (TOTP) and copy a code in one click from the toolbar popup. Open the full list to search by name or category, group your entries, and drag cards into the order you want. Each card shows when its current code will expire. • Add an entry using a setup key or an otpauth:// link. • Import compatible text exports from other authenticators. • Export a JSON backup and restore it on another computer. • Save a readable TXT list of setup keys grouped by category. • Switch between English and Traditional Chinese. Codes are generated on your device, and saved entries are encrypted in your Chrome profile. No account sign-in is required. JSON backups and TXT downloads contain unencrypted setup keys.
