What Makes a Strong Password?
A strong password is your first line of defense against cyber attacks. It should be long, complex, and unique to each account. Our password strength checker evaluates six key criteria to ensure your passwords meet modern security standards.
Strong passwords significantly reduce the risk of unauthorized access to your accounts, protecting your personal information and digital assets.

Frequently Asked Questions
How often should I change my passwords?
Change passwords immediately if there's a security breach, every 90 days for sensitive accounts, and annually for less critical accounts. Focus on strength over frequency.
Are password managers safe?
Yes, reputable password managers use strong encryption and are much safer than reusing weak passwords. They generate and store unique, strong passwords for each account.
What is two-factor authentication?
Two-factor authentication (2FA) adds an extra security layer by requiring a second form of verification, like a phone code, in addition to your password.
Can I use passphrases instead of complex passwords?
Yes, long passphrases with 4-6 random words can be both secure and memorable. Add numbers and symbols for extra strength.
