Use a unique password for every account.

Never reuse passwords across services.

Consider using a password manager to keep track of your credentials securely.

PINs are convenient but less secure than full passwords.

Avoid obvious sequences like 123456 or repeated digits.

Use a 6-digit PIN minimum when possible.

Passphrases rely on length for security rather than complexity.

A 24-character lowercase-and-numbers password is very hard to crack.

Easier to type on mobile devices since no shift key is needed.

WiFi passwords should be at least 12 characters with mixed types.

Exclude ambiguous characters so guests can read and type the password easily.

Print or share it as a reference page.

API keys should be long and alphanumeric for compatibility with most systems.

Avoid special symbols that may need URL encoding.

Rotate keys regularly and never commit them to version control.

Memorable passwords trade some security for usability.

Good for low-risk accounts where you need to type the password frequently.

For high-security accounts, use a longer password with symbols.

Maximum security passwords are essential for primary email accounts, financial services, and password manager master passwords.

At 40 characters with all types, this is virtually unbreakable by brute force.

Always store in a password manager.

Developer tokens should be long and URL-safe (no special characters).

Store tokens in environment variables, never in source code.

Use separate tokens for development and production environments.
