Been having the same problem every single day for 2 years ever since I installed LastPass. I use the same account in multiple browsers (Chrome and Opera). In Chrome is works almost perfectly, but in Opera I constantly get logged out. But the most annoying thing is that it pops up a new tab asking to login ALL THE TIME.
I have double and triple checked that every possible setting to prevent logout is disabled. I googled and tried every solution I could find. I tried disabling plugins and stuff. Nothing helps. This software is buggy. And while I am writing this I see LastPass continue to open new tabs in Opera.
For example yesterday I went to bed and let Opera open. Today I woke up to HUNDREDS of tabs opened by Lastpass:
Garbage product. Garbage security. Garbage support.
I'm done.
Bought BitWarden and moved everything.
Good riddance LastPass, I won't miss you
