Make sure these boxes are checked before submitting your issue - thank you!

• I have checked the superset logs for python stacktraces and included it here as text if any
• I have reproduced the issue with at least the latest released version of superset
• I have checked the issue tracker for the same issue and I haven't found one similar

Superset version

0.25.5

Expected results

I could set session timeout in config.py, and when the time is out , user should login again.

Actual results

I don't know how to set it

Steps to reproduce

What's your advice?

We use flask-appbuilder which uses flask-login, so all you have to do is add these configurations to your superset_config.py:

If you have time please add an FAQ entry in the docs!

@mistercrunch OK!

set PERMANENT_SESSION_LIFETIME in the Superset config file

Is there a way where we can set some alerts before the session timeout ?

See context from https://stackoverflow.com/questions/34118093/flask-permanent-session-where-to-define-them

In superset, you can use FLASK_APP_MUTATOR to enable session.permanent = True to make Flask setup session expiration time. see my PR #16286
