Manager ( password )

I installed manager since the 25th of April and it never asked me about my info even if I restart my pc and close manager … everytime I open pc it opens normally without asking for any info
I’ve got alot of accounts’ info please we must find a solution
Unfortunately and idk why when I tried to open today the manage told me password you have entered is incorrect and I didn’t change it or use it before .
Is there anyway to get back my password ?
