What is Two factor Authentification?
Two-factor authentication adds a layer of security by requiring two different forms of identification before granting access to an account or system. This reduces the risk of unauthorized access, as an intruder would need more than just a password to log in.
How does it works?
Two-factor authentication combines two distinct types of identification to verify user identity:
1. First factor identification: The user enters something they know, often a password or PIN.
2. Second factor identification: The user provides something they have (like a message providing them with a confirmation code) or something they are (like fingerprint, facial recognition).
Applying these two factors makes access more secure, because even if one factor is compromised, access is still protected by the other. For example, even if someone has your password, they can’t access your account without the second factor, usually sent via SMS, or authenticator app.
