Recovery codes

Enrolling in 2FA issues ten one-time recovery codes. Each works exactly once at the sign-in code prompt, in place of an authenticator code. They exist for one scenario: your authenticator device is gone and you still need in.

Shown once, never readable again

The codes are displayed a single time, at enrollment (with download and copy buttons). After that SleeveFolio keeps only a scrambled one-way version of each code — nobody, including us, can read your codes back. If you didn’t save them, regenerate.

Regenerating

The two-factor card under Settings → Account regenerates a fresh set of ten at any time. Regenerating invalidates every old code immediately — saved copies of the old set become useless paper.
