Overview ¶
Package otpcode is the TOTP arithmetic shared by every second step (a User's Second factor, ADR 0020, and a Staff member's TOTP, ADR 0026): new keys with their QR code, and matching a submitted code against a secret at a clock. It holds no state: each caller stores the last accepted time step itself and makes the conditional write that makes a code single-use.
