KeePass XC :)

Not desktop only, KeePass uses an encrypted file, all you need is a way to decrypt it. You can store it in iCloud or whatever you like to sync files between devices.

iOS has a good open source app KeeForge to open the encryped password files. I use SyncTrain on my phone to connect to my SyncThing network.

It's unfortunate that its a bit fragmented but there are Android / iOS complements as well - respectively keepassDX and keepassium.

There are several good Android Keepass clients, and Syncthing apps too.

Look longer :)

There are Pros and Cons. Cons: generated passwords have less flexibility, not being able to add custom fields (ie backup codes or PIN), can’t store key files (unless you copy and paste contents into Notes section, which doesn’t redact it), no independent master vault password like 1Password.

Pros: it’s free and will probably be free forever, can store and generate TOTP codes, biometric unlock, very easily syncs between devices, great integration on macOS and iPhone/Pad, easy sharing of password to family members without them needing a subscription.

I have been a 1PW user for 10+ years but earlier this year started the long transition to save $10/month for the rest of my life which turns out to be a non-insignificant amount.
