Hey there @nihalilu!
Let me ask a few questions so I can understand your usecase better. Basically when rememberLastLogin was set to false you got immediately logged in without being prompted? When you set it to true everything was fine right? Firstly you had your account linked then you unlinked it and after that you’re not displayed with the login page and you’re just logged in?
Have in mind that rememberLastLogin option you mention is a Lock option only applicable in certain scenarios. I believe the important question to answer would be what’s the duration of an SSO session established by Auth0 when an end-user authenticates (independently of how Lock is configured to try to use it or not). with this in mind I think you should check this of the reference documentation as it goes over the lifetime of the session and how you can influence certain aspects of that lifetime.
Thanks for providing additional clarification!
