    Useless if you can not come up with syncing solutions through various third party plugins and addons (good luck finding any updated ones). If you love wasting time and constantly copy pasting files between directories, this is your gold mine.

    I use it for long years. First only at windows and now android too. I sharing the same cloud database and this made my use very easy and fast. I use a very very long master pass for safety and force me to remember but if i dont, i always can take a fast look and solve the problem.

    KeePassXC is the best KeePass port for Linux (and perhaps MacOS). On Windows, KeePass 2 (original) is unbeatable.

    KeePassXC is the best cross-platform Bitwarden alternative. It is open source like bitwarden but makes storing your passwords offline easy and secure. Also it is totally free!

    It is the best alternative for BitWarden because it's cloud based, thus auto sync across devices. Open source. Privacy focused.

    While Proton has existed for very longtime. Proton Pass service is fairly new compared to BitWarden. So some feature might be lacking. UI/UX feels more modern but usability is simply okay. This is totally subjective.

    Premium feature comes free if you already have Proton Unlimited for their other services.

    Some negatives:

    • No self host option
    • More expensive
