What makes a strong password?
- Use at least 16 characters; length matters more than complexity.
- Use a different password for every account so one breach doesn't expose the rest.
- Avoid guessable details like birthdays, names or sports teams.
- Store passwords in a password manager instead of memorizing them.
Stop remembering passwords one by one.
