Make a list
Generated on your device with crypto.getRandomValues. Nothing is sent or stored. Passphrases use the EFF long word list (7,776 words).
A username that does not contain your name, birth year or town keeps your accounts harder to link and your security answers harder to guess.
Make a list
Made on your device from a hand-picked list of friendly words. Nothing is sent, so names are not checked against existing accounts.
Has this password appeared in a data breach?
Optional, and only when you press the button. Your password never leaves this device: it is turned into a SHA-1 fingerprint here and only the first 5 of its 40 characters are sent to Have I Been Pwned. The list of matching fingerprints comes back and is compared on your device.

Questions
How do I verify a file checksum?
Drop the file, then paste the checksum from the download page into the verify box. If it does not match, download the file again from the official source.
Which hash should I use?
SHA-256 for verifying files. MD5 and SHA-1 are only for legacy checksums — they are broken for security purposes.
Are my files uploaded to your servers?
No. The tool runs entirely inside your browser — your files are processed on your own device and never sent to In-Right or anyone else. You can even disconnect from the internet after the page loads and it still works.
