E.g. A home PC used only by me in a house I own with my partner.
2 weeks session timeout + 4 devices = Needing to re-login somewhere every 3-4 days.
For reference, Facebook tokens last 60 days and have auto refresh. I've never had to login on Facebook except for a new device. This is how it should be done!
It's higher risk to be re-entering your master password multiple times a month. Keyloggers, watching over someones shoulder, hackable keyboard bluetooth etc. I should never have to type my master password in public, for example.
