Hi porum,
You may want to make sure "Stay logged in" is checked in the login screen under the username/password.

If that doesn't help, can you contact us so we can help more specifically? Thanks!

Having the same issue. Have to log in about once a week since I have the Mac desktop app. There is no pattern detectable why this is necessary. "Stay logged in" is checked, of course.

Hi fxf8klc,
You should stay logged in for 1 month with "Stay logged in" checked, so you may want to remove and reinstall the app if this continues.

Keep us posted on what you find!

I get asked to log back in frequently, too. I've reinstalled the app and always have "Stay logged in" checked.

Also seeing this. Maybe it's because I'm logged into RTM on too many devices?

It's definitely more than once a month for me being asked to login. I'd say at least weekly. Because I use RTM mostly on iPhone for me it's nearly any time being asked to login when I use it on desktop. That's not productivity. I don't want this on my device that I secured well.
