* Syncs between devices. I can login to my accounts in all my devices. If I can access my Dropbox account, I can access everything else with the master password.
* Auto password generation. I don't ever even bother looking at the passwords. Just generate something like 32 characters with all ASCII characters, including "special" characters. This goes a long way.
Having used KeePass (with Dropbox sync) since ~2018 I don't even know how people operate without a password manager. It's so intensely convenient. Just dump all the info in the database. I can even take notes in my database. Write my credit card number, SSN, other private info. Put SSH keys. Put website info. Describe where I put my tax documents. Password manager is a pointer to everything else.
