A long memorable passphrase is pretty good as a master password for a password manager.

Afaik they‘re working on deattach Pass from the other Services, until then I‘ll keep BW + Authy as a backup
I agree with other comments, a long passphrase coupled with a couple of yubikeys would be great. Even more when a separate validation for Pass come to production. Hopefully soon.
I'm a little worried about this too... With 1Password, I'm fine with having a master password I can remember, since I know it's only useful to an attacker if they also have access to one of my devices, or know my Secret Key. That means that a targeted, high-effort attack is necessary to get in. Proton Pass just being protected by a single password makes it way easier to run remote attacks.
You can use 2fa with proton as well. I have yubikeys configured for instance.
