Where 6238 fits
Why 6238 is special
Every authenticator app showing a six-digit code on a thirty-second cycle is this document, and the codes fail when a phone's clock drifts.

Strength 0.50, confidence "high".
Technology & computing
RFC 6238 extends HOTP by replacing the counter with a time step, commonly thirty seconds. Verification depends on both parties agreeing on the time, so clock drift causes failures.
