I really like Bitwarden to manage my passwords, could I use it to manage my contacts too?
Is it valid to use a password manager as a contacts and password manager too?
information such as: email1 or email2, phone1 or phone2, name, website…
I don’t think it’s a particularly good idea, simply because it’s not designed to act as a contact manager. That said, if you want to do that, there’s nothing in the T&Cs that prevents you.
