Frequently Asked Questions
How does the password generator create secure passwords?
The generator combines randomly chosen characters from your selected categories: uppercase letters (A-Z), lowercase letters (a-z), digits (0-9) and special characters (!@#$% etc.). The algorithm ensures that each selected category appears at least once in the password, after which the characters are randomly shuffled (Fisher-Yates shuffle).
Are my generated passwords stored?
No. The password generator runs entirely in your browser (client-side). No passwords are sent to a server or stored. Once you leave the page, the passwords are gone — unless you exported them.
What password length is recommended?
For maximum security, a password length of at least 16 characters is recommended, using all character types (uppercase, lowercase, digits and special characters). For testing purposes, you can set any desired length between 4 and 128 characters.
Can I generate and export passwords in bulk?
Yes, you can generate up to 10,000 passwords at once and export them directly to Excel (.xlsx), CSV, or JSON. This is particularly useful for filling test databases, creating test accounts, or setting up test automation pipelines.
What do developers use a password generator for?
Developers use password generators for creating test accounts with realistic passwords, testing password validation rules, filling seed data in test databases, load testing with unique credentials, and testing password strength indicators in forms.
