Online accounts and filling in forms

In short: For many services you create an account (email, password) and fill in forms. Give only what is needed and use a separate password for every account.

In more detail: Required fields are usually marked with *. After registering you often confirm your email address via a link. You can usually delete an account later.

In Depth

• Registering: Email, password, maybe name. Skim the terms of use and privacy notice.
• Confirmation mail: Click the link, otherwise the account stays inactive. Check the spam folder.
• Autofill: Browsers can fill in address and password. That saves time but requires a secure computer.
• Two-factor sign-in (2FA): Extra code via app or SMS. Greatly increases security.
• Give data sparingly: Date of birth and phone number only when really needed.
• Signing out: Always sign out on other people’s computers.
