What this password generator does
This tool creates a random password using letters, with optional numbers and symbols. Longer passwords are usually harder to guess than short ones.
Example: choose 20 characters with numbers and symbols for a password that is harder to reuse or guess than a short word-based password.
Use unique passwords for each account and store them in a reputable password manager. For adjacent utilities, browse the Generators category.
Common mistakes
- Reusing the same password across multiple accounts.
- Choosing a short password because it is easier to type.
- Removing symbols when the account allows them and you can store the password safely.
- Sharing generated passwords through insecure messages or documents.

Frequently Asked Questions
Common questions about Password Generator and how to read the result.
Is it safe to use this password?
The password is generated in your browser, but security also depends on where you store it, whether you reuse it, and the account's protections.
What length should I choose?
Longer is generally better. Use the longest length your account supports and that your password manager can store.
Should I include symbols?
Include symbols when the site allows them. Some older systems restrict symbols, so check the account rules.
Can this guarantee account security?
No. Password strength helps, but account security also depends on reuse, phishing, two-factor authentication, and service-side protections.
Should I memorize generated passwords?
Usually no. A password manager is better for long unique passwords.
Is this a passphrase generator?
No. This tool generates character-based passwords, not word-based passphrases.
