I am working on a SPA application using the implicit flow with oauth 2 and B2C. I configured B2C so my users can log in using local accounts (email/password). Because of the nature of the implicit flow, users must be redirected to the log in page in order to authenticate and get a new access token every time they decide to visit my web site. I can then use that token when calling my API. My question is this: Why is there no "Remember me" checkbox on the login page when using B2C and local accounts in order to avoid users to type their email and password every time they log in?
