Create credentials and share links without confusing encoding with secrecy
Connect local password generation and checking with QR, confirmation links and hashes while separating public payloads from secrets.
Use a unique password and store it in a password manager
Choose adequate length and randomness, never reuse it and enable multi-factor authentication. A local readiness check neither searches breach databases nor guarantees security.
Do not place a secret in a QR code
A scanner can read the embedded payload. QR is suitable for intentionally shared links or text, not passwords, tokens or personal data.
An encoded share link does not hide its destination
The share-link tool stores the destination in Base64URL and asks the recipient to confirm the domain. It is not encryption and can be longer than the original URL.
A hash is neither encryption nor password storage
A SHA-256 digest is one-way in design but does not conceal guessable input and is not a password-hashing scheme. Use it only for a clearly specified workflow.
