Create strong, random passwords in seconds. Customize length, character types, and exclusions to build unique credentials that improve your security on every account.
Why use a Password Generator?
Reusing or guessing passwords is a leading cause of account compromise. A dedicated Password Generator removes human bias and produces truly random strings that are far harder to crack. Attackers often rely on dictionary lists, leaked credentials, and predictable patterns like seasons or keyboard walks. Randomly generated passwords avoid these pitfalls and increase the number of possible combinations by orders of magnitude, dramatically strengthening your defenses.
Beyond raw randomness, a generator lets you tailor passwords to site requirements. Some services demand a minimum length, others require symbols, and a few disallow certain characters. By selecting the right options, you can meet those rules without sacrificing security or memorability where it matters.
How to use the Password Generator
Step-by-step
- Choose a password length. We recommend at least 16 characters. For critical accounts like email or banking, consider 20–24 characters.
- Select character types: lowercase, uppercase, numbers, and symbols. More types usually mean a larger pool and stronger passwords.
- Optionally exclude similar or ambiguous characters if you want better readability or need to avoid lookalikes such as 0 and O.
- Use the “Require at least one of each selected type” option to satisfy sites that enforce complexity rules.
- Enter any characters to exclude if a site bans them. Then generate one or many passwords as needed.
Understanding strength and entropy
Password strength is commonly estimated using entropy, measured in bits. Entropy grows with both length and the size of the character set. For example, 16 characters drawn from 62 possible characters (a–z, A–Z, 0–9) have far more combinations than 12 characters from only lowercase letters. Our tool provides an approximate entropy estimate to help you gauge strength at a glance.
Best practices for secure passwords
- Prefer length over complexity: a longer password with varied characters is usually stronger and more resilient to brute force.
- Use a unique password for every site to prevent domino-effect breaches.
- Store passwords in a reputable password manager instead of trying to memorize them.
- Enable multi-factor authentication (MFA) wherever available for layered security.
- Rotate passwords after a suspected breach or when required by policy; otherwise, avoid unnecessary changes.
Readability vs. security
Some users prefer to avoid lookalike characters, such as i, l, 1, L, o, 0, and O. Excluding them can reduce mistakes when typing, particularly on mobile devices or with small fonts. This slightly reduces the character pool, but if you maintain a strong length (e.g., 16+), your passwords remain robust.
Meeting site-specific requirements
Websites vary widely in what they accept: some insist on symbols, while others reject them; a few limit which symbols are allowed. The Password Generator’s exclusions and the “require at least one of each type” option help you comply without trial and error. If a password is rejected, adjust the settings—remove specific characters or toggle ambiguous symbols—and regenerate instantly.
Generating multiple passwords
Need to update several accounts? Generate multiple passwords in one click and assign them across services. This saves time while ensuring each login remains unique. Combine this with a password manager to store and autofill credentials securely.
Security you can trust
Our generator uses cryptographically secure randomization to select characters, helping you avoid patterns that simple random functions might introduce. The result is a set of unpredictable, high-entropy passwords tailored to your needs.
Take control of your security today: choose a strong length, include varied character types, and adopt a password manager. With the Password Generator, building and maintaining safe credentials is faster and easier than ever.
