Security tool
Free password generator
Create a strong random password with a configurable length and character pool. Aegis generates the result in your browser and gives you immediate entropy and strength feedback.
Aegis uses the browser’s cryptographic random-value API for this tool. Never reuse a password, and do not paste a generated password into an untrusted page.
How to generate a password
- Choose a length. Use the length control from 8 to 64 characters.
- Select character types. Combine lowercase, uppercase, numbers, and symbols, with an option to exclude ambiguous characters.
- Generate and copy. Review the strength and entropy indicators, then copy the result when you are ready.

Password generator FAQ
Common questions
Is this password generator free?
Yes. The Aegis password generator is available in the browser without an account.
Are generated passwords sent to a server?
The password generation logic runs in the browser. Aegis does not need a password-generation request to create a result.
What password length should I use?
Use the longest length accepted by the service you are signing into. A longer password with more character types generally provides a larger search space.
Does the strength label guarantee safety?
No. The label is a local estimate based on the selected length and character pool. Account security also depends on the service, storage, and whether the password is reused.
