What this tool does
Create random passwords with configurable length and character sets. Generation uses the browser’s cryptographically secure random number generator when available, and the password is never sent to ToolsDiary.
A password generator is most useful when paired with a reputable password manager, unique passwords for every service and multi-factor authentication. Strength depends on randomness and length, not on making a password visually complicated in a predictable way.
Useful for
- Create unique passwords for new accounts.
- Generate temporary credentials for development environments.
- Avoid reusing memorable passwords across services.
How to use it
- Choose the desired password length.
- Select the character groups you want included.
- Generate a password using secure browser randomness.
- Store it immediately in a trusted password manager rather than a plain text note.
Practical tips
- Long unique passwords are generally more valuable than clever patterns.
- Use multi-factor authentication on important accounts.
- Never reuse passwords across services.
- Do not send generated passwords through insecure messaging channels.
Frequently asked questions
Does ToolsDiary store generated passwords?
No. Password generation happens in your browser and the value is not transmitted to our server.
What length should I choose?
Longer is generally stronger. Follow the requirements of the service and prefer a password manager so length is not a memorization burden.
Why is there an option to exclude ambiguous characters?
Some users must manually transcribe passwords. Excluding look-alike characters can reduce transcription errors, although it slightly reduces the character set.
