To modify your password click: on your Avatar, the cogwheel symbol, Password & Security. Or if you've forgotten your password, logout (if your already logged in via autofill), then beneath the login prompt click "Forgot Password".
If you need help creating a password you can use a random password generator such as

To ensure your account is secure we suggest using a 2FA (Two Factor Authentication) app
To turn on 2FA: click: on your Avatar, the cogwheel symbol, Password & Security, choose Two-Step verification. You can select verification via email (less secure and may be blocked by your ISP) or via an authenticator app (such as Google Authenticator or Microsoft Authenticator).
The email verification is almost worthless if a scammer already has access to your email, so we do not recommend this method. 2FA via an Authenticator app works flawlessly and exceptionally well. You only get prompted once a month for the verification code.
