I use Bitwarden, which I have configured to use the EU servers (bitwarden.eu). I have considered self-hosting Vaultwarden or requesting access to Tux.pizza’s instance, but I reckon Bitwarden themselves probably know what they’re doing.
Proton Pass looks promising, and it’s the logical choice as I already use ProtonMail, ProtonVPN, and Proton Calendar; but I’m happy with what I’ve got.
