About this tool

Create a Base32 TOTP secret with issuer and account, choose digits, period and algorithm (SHA1, SHA256, SHA512) and scan the otpauth:// QR code with Google Authenticator, Aegis, 1Password or Bitwarden. The current code counts down live next to the previous and the next one, and a check tells you whether a code is valid within the clock-drift window (RFC 6238).

Meant for testing your own 2FA implementation: only use test secrets here – secrets for real accounts belong on the server.
