Next to Recovery codes, click Show codes. You may be asked to confirm it's you.
The row tells you how many are left, for example 15 of 16 left. A code you have used is crossed out and marked Used:Download, Print and Copy only include the codes you haven't used yet.
Recovery codes are not a sign-in method on their own. They don't appear until you have turned on an authenticator app, a passkey or a security key.
If you turn off two-factor authentication, your recovery codes are deleted too.
Nobody at Shorter Loop can see your codes. We keep a fingerprint (a one-way hash) of each code, plus an encrypted copy that only your Show codes request can open.
If you have lost every method and every recovery code, see Troubleshooting.
