that are good suggestions. my bank accounts all require two steps authentications, with the second one being mostly auth via mobile app, so that part is enforced and always keeps the account secured better.
I do have one concern with the Proton account itself, as you wrote "no all eggs in one basket" rule of thumb. With the Pass, I have the 2FA integrated together with passwords (not for bank accounts) - a little risk in here with a gain on convenience.
Though I certainly do not store my Proton password in it, keeping it memorable and more than 40 characters long makes me feel safe. Im not sure what 2FA app to use for the Proton tho, would you recommend anything? I cannot use a physical key, as my devices have different USB connectors and I cannot have a one key for all.
