How to Create a Strong Password: A Practical Guide

A strong password is long, unique, and difficult to guess. The most important rule is not complexity alone: do not reuse the same password across different services.

What makes a password strong?

Use a long random password or a memorable passphrase with several unrelated words. A password manager can generate and store unique credentials for every account. Enable multi-factor authentication whenever it is available.

Avoid names, birthdays, predictable substitutions such as @ for a, and reused passwords. If one reused password appears in a breach, attackers may try it on other services.

Generate a password safely

Use Casetivo's Strong Password Generator to create a random password with the length and character types you need. Save the result in a trusted password manager rather than a plain text note.

FAQ

How long should a password be?

Longer is generally better. Use the maximum length supported by the service, especially for important accounts.

Should I change passwords regularly?

Change a password when you suspect compromise, receive a breach alert, or reuse it elsewhere. Unique passwords and MFA are more valuable than arbitrary frequent changes.
