Strong Customer Authentication (SCA) provides more protection against fraud when you access your online accounts or shop online. Instead of being asked for one factor of identification like a password, SCA provides more protection as it uses two out of three possible factors of identification (sometimes referred to as 2 Factor ID) to confirm it really is you.
The three factors are - something you know (e.g. a password or PIN), something you are (e.g. a fingerprint), or something you have (e.g. a registered mobile phone).
