What are backup codes?
Ten single-use codes that let you sign in if every device with a passkey is unavailable.
Quick Steps
- 1 Generate from Security (Passkeys) -> Backup codes.
- 2 You will see the 10 codes ONCE. Save them immediately.
- 3 Print the page, or paste them into a password manager.
- 4 Each code works exactly once.
- 5 When low, click Regenerate to get a fresh batch (invalidates the old batch).
Backup codes are a safety net. If you lose every device with a passkey enrolled, a backup code can still get you in. Bizity generates ten at a time and stores only bcrypt hashes -- you see the plaintext exactly once, at generation, and must save them yourself.
Best practices:
- Print the page and store the printout somewhere safe (home safe, file drawer).
- Paste into a password manager (1Password, Bitwarden) under a secure note.
- Do not email them to yourself -- email gets compromised, defeating the purpose.
- When you run low, regenerate a fresh batch. The old batch is invalidated automatically.
To use a backup code at sign-in: during the passkey challenge, click Use a backup code instead and type the code. It will sign you in and mark that specific code as used.
