Logging in with an SMS code is an industry standard in messaging, but if you're looking for more security or have reasons to doubt your mobile carrier or government, we recommend protecting your cloud chats with an additional password.
You can do this inSettings > Privacy and Security > 2-Step Verification. Once enabled, you will need both an SMS code and a password to log in. You can also set up a recovery email address that will help regain access, should you forget your password. If you do so, please remember that it's important that the recovery email account is also protected with a strong password and 2-Step Verification when possible.
Check this outfor tips on creating a strong password that is easy to remember.
You can also set up aPasskeyto log in without an SMS code at all, using your device's PIN, fingerprint or face scan.
