Authentication 9

The level of assurance required for confirmation of identity should be assessed. In some cases different levels of authentication may be needed (e.g. two-factor authentication for some users, but not others), and re-authentication should be considered for some important functionality (e.g. changing password, making a payment, deleting an account), especially where weaknesses have been accepted to reduce application friction for users (e.g. having longer session timeouts, allowing guest check-out, having remember-me functionality).

How to play?

Claudia can undertake more critical functions because authentication requirements are too weak (e.g. do not use strong authentication such as two factor), or there is no requirement to re-authenticate for these
