Proton is the service you need, from password manager to protonmail, and much more. This is the one, I will not go without it.

I used to use Bitwarden and the old Firefox version that would work on your phone too. I now trust Proton Pass for it. Integration of the alias emails is wonderful.

is a good extension.

👍 My favorite password manager. Love it. Very easy to use. I installed it for my family members as well
