There are a couple of reasons for being logged out of your account.
The first possibility is you logged in from a different device, without logging out of the other device first. Ubersuggest will detect that and block any simultaneous access, and you will see a pop-up similar to this:

The second reason is the tool forced a sign-out, due to inactivity.
Forcing a sign-out is pretty standard in the industry. It's a matter of security. It is a matter of cost, too; an open session might request more data than a closed one, so we want to keep our costs in check to offer the best price in the market.
If you have any questions, please reach out via chat or email us at firstname.lastname@example.org.
