I use the Strongbox app on iOS [0] and the KeepassXC app my Linux laptop. The passwords.kdbx file sits on my Onedrive, which the Strongbox app can access. On Linux I use a Onedrive client [0] that I use to sync several folders within my home folder. Strongbox supports both Keepass and pwSafe database formats. It also integrates well with iOS, with autofill supported (also supports Yubikey unlock and Apple Watch unlock).
This discussion is about an open source password manager. I wonder why you are recommending a closed source software? Are you aware that many people prefer open source for security software for a reason?
Correct. I did not realise this and am disappointed, having paid a pretty penny for the lifetime license. Reading the github thread, the surreptitious way they changed things is a bit of a dick move.
