Generators
Create a long, random password locally with cryptographically secure browser randomness.

Safer accounts
Use a different password for every account and save it in a reputable password manager. Turn on multifactor authentication wherever it is available.
Good practice

Common questions
The generator uses the browser's cryptographic random-number API and rejection sampling rather than Math.random.
No. Generation and copying happen in the current browser and no password is sent to Tool Packer.
No. Use a separate password for each account and store it in a reputable password manager.
Generation happens entirely in this browser. Tool Packer does not receive or store your password.
The tool reads and processes this input in your browser. Tool Packer's application server does not receive the input or generated result.
