Account Security tips

πŸ”

A good password for a new account should be at least 12 characters and score "Strong" here. This means an estimated crack time in the billions of years.

πŸ’‘

Use a passphrase β€” 4 random words like "coffee-river-lamp-moon" β€” it's easy to remember, has high entropy, and passes all strength checks.

🚫

Avoid using personal info: names, birthdays, favourite teams. These are guessable through social engineering even if the password looks complex.

πŸ”‘

Use a unique password for every account. A password manager generates and stores strong passwords for you so you only remember one master password.
