How OTPs Actually Expire ⏱️ Authenticator codes and SMS codes expire in two very different ways. Authenticator apps calculate the code from a secret key shared at setup and the current 30-second time block, using HMAC-SHA1. When the block changes, the code changes. SMS and email codes are random numbers stored in Redis with a 2-minute expiry, and once the key expires, the code is rejected. Authenticator app or SMS code, which do you trust more? Tell us in the comments 👇 #OTP #TOTP #2FA #Authent
