I've been using BItWarden for years with absolutely no problems. That can't be said for the password manager I used prior to BW - Bitdefender - which was causing very odd problems and a security hazard that BD were quite unhelpful and rude about ("our software is bulletproof, your problem is elsewhere..." you know the drill). This was shortly before BD eliminated their free tier, so I switched to BW, the problem went away (with no changes to all the "elsewhere" parts of the system), and has worked perfectly since. A+.
