This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
TOTP credentials are also based on a shared secret known to both the client and the server, creating multiple locations from which a secret can be stolen. [4] An attacker with access to this shared secret could generate new, valid TOTP codes at will. This can be a particular problem if the attacker breaches a large authentication database. [5]

The Secure Remote Password protocol (SRP) is an augmented password-authenticated key exchange (PAKE) protocol, specifically designed to work around existing patents. [1]Like all PAKE protocols, an eavesdropper or man in the middle cannot obtain enough information to be able to brute-force guess a password or apply a dictionary attack without further interactions with the parties for each guess.
