I'm using the the Python web framework Flask. I use sessions in my app. For my app called main, I've got the setting main.permanent_session_lifetime = timedelta(days=5), so that a user will remain logged in for 5 days after logging in. But even an active user will be logged out after 5 days. I would like the expiration time to reset each time they visit the site, so you get logged out only after 5 days of inactivity. Most sites work this way. How do I do that with Flask?

This can be done easily by adding expires=expirationDate in UTC separated by semicolon from the name=value, as seen in the following example: document. cookie = "username=Max Brown; expires=Wed, 05 Aug 2020 23:00:00 UTC"; document.
You can extend the life of a cookie beyond the current browser session by setting an expiration date and saving the expiry date within the cookie. This can be done by setting the 'expires' attribute to a date and time.
Cookies with an expiration date in the past will be removed from the browser. To remove a cookie, you must set it's set its expiration date in the past. This will signal to the browser that the cookie should be removed.
The default time for a Cookie to expire is 30 minutes. The default Expires value for a cookie is not a static time, but it creates a Session cookie. This will stay active until the user closes their browser/clears their cookies. You can override this as required.
You can renew the session to the client at each request using a @before_request handler.
Try the following:
@app.before_request
def func():
session.modified = True
Should be enough with:
from datetime import timedelta
# User will be logout after this time of inactivity
PERMANENT_SESSION_LIFETIME = timedelta(minutes=30)
SESSION_REFRESH_EACH_REQUEST = True
