All Proton mobile Apps now support FIDO2 for 2FA — grab your security keys!
from the team:
Hi everyone,
We've heard your requests and are excited to announce that FIDO2 support is now live for all Proton mobile apps! This means you can use security keys like YubiKey to add a layer of phishing-resistant protection to your account. Here’s how to add a security key to your account using the web app:

After adding security keys, you can use them to authenticate on mobile when signing into all Proton mobile apps.
Thank you to everyone who's been asking for this feature. We're always working to make Proton more secure and user-friendly, and your feedback is invaluable in helping us get there.
What's next?
Soon, we'll provide the option to disable the Authenticator App for those with registered security keys, so stay tuned!
Give it a try and let us know what you think!

So if I add a security key on my phone, I'll have to use it on the web too? Or would I need to make sure I have multiple keys so I can log in with either one?
Not sure I understand the question. A key can be used on Web as well as on the mobile apps now, instead of TOTP (which however cannot be yet disabled). It is generally advised to have a multiple key pair, incase one is lost / defect.
I thought I read that some phones can be the security key, hence my confusion as to how would that work
