Authentication Using OTP

OTP (One-Time Password) is a login system that uses a temporary code valid for only one login. For security reasons, this code changes every few seconds (in the Authenticator app) or every few minutes (a code sent via email). The choice between using OTP via an authenticator or email depends on the user’s preference.

The user is required to verify themselves using OTP at every login. After entering their email and password, the system requests a code displayed in the Google Authenticator app or in an email. After entering the correct code, the user gains access to the system.
