Your password is stored very securely. They are uniquely salted and hashed with a modern memory-hard hashing algorithm. The primary database where these hashes are stored is run on hardware with full-disk encryption and encrypted backups.
If you are very worried about security though, all you really need are strong, single-use passwords. It really doesn’t matter how a service stores passwords if you only use them once. And while 2FA can add an additional layer of security, in practice an attacker that has access to your single-use password in all likelihood will have access to your 2FA method.
That said, we plan to add some form of 2FA/MFA in the near(ish) future.
