Good way to implement a "Remember login" logic?

[laurenzcodes]

Is your feature request related to a problem?
I can't find a way to natively implement a checkbox to allow "saving the login".

Describe the solution you'd like
I would like any option to allow saving the login info so authenticating is faster

Describe alternatives you've considered
One option would be to add a timeout after the user pressed "login" to allow the device native "save password in keychain" to be displayed for longer and isn't being skipped (without the user having time to save it - which is currently the case)

Android saves the auth session in chrome more consistently, so it auto-logins more often by itself - but not 100% of the time.
