Password Tools
What is this tool?
A two-step password workspace: the Generate tab builds a random password to your length and character-set rules, and the Check Strength tab evaluates it immediately without you needing to retype or copy-paste it.
When to use it
- Creating a new account password that actually meets a site's strength requirements
- Checking whether an existing password is strong enough before reusing it
- Generating and verifying a passphrase for a password manager's master password
- Comparing a few candidate passwords for a shared or service account
- Teaching or demonstrating what makes a password weak or strong
How to use it
- 1Open the Generate tab and set your desired length and character types (uppercase, numbers, symbols)
- 2Click Generate to create a random password
- 3Switch to the Check Strength tab — the generated password carries over automatically
- 4Review the strength score and feedback
- 5Copy the password once you're happy with both its randomness and its strength
Frequently asked questions
Does the generated password get sent anywhere?
No — generation and strength checking both run entirely in your browser; nothing is uploaded or logged.
Why does my password carry over automatically between tabs?
The workspace is designed so you don't have to retype or copy-paste — generating a password immediately fills the strength checker with it.
Can I check the strength of my own password instead of a generated one?
Yes — the Check Strength tab accepts any text you type or paste, not just a password generated in the first tab.
What does the strength score actually measure?
Length, character variety, and common patterns — it's an estimate of guessability, not a guarantee against every attack.
