Original GitHub issue: https://github.com/healthchecks/healthchecks/issues/1063

Every time my login times out, I am blasted with a white screen before I login.

This change could be a simple environment variable that enables dark mode globally (by default, meaning users can still use white mode if they chose so).

Thanks for the suggestion.

How about instead extending the session cookie age, so the session doesn't time out?

There's a SESSION_COOKIE_AGE setting, with the default value set to to 2 weeks. On Healthchecks.io I've set it to one year. This means in practice I get never automatically logged out (unless I don't visit the site for more than a year ;-).

Healthchecks does not currently read SESSION_COOKIE_AGE from an environment variable (setting an environment variable with this name currently has no effect), but we could look into doing that.

Yeah, that would solve my particular issue. So to clarify, I would only get logged out, if I don't open HC for a year (with the variable set to a year obviously)?

I would honestly prefer to keep it at 2 weeks, but with that logic - so if I keep opening HC every 13 days, the cookie is refreshed and the session is extended - unless that is how it currently works?

I don't think I've ever went for 2 weeks without opening the page at least once, but I'm not 100% sure.

I think I was mistaken about session expiry – Django sessions do not auto-refresh. If the session cookie expiry is 2 weeks, you get logged out after 2 weeks even if you regularly use the site. IIUC.

I think I haven't noticed logouts due to expired session, because on Healthchecks.io the expiry is 1 year, and I regularly log out and log into throwaway accounts for testing, so the 1 year expiry never comes around.

I'll look into implementing session refresh.
