Frequently asked questions
Is this password generator secure?+
Yes. LinkMeow uses the native Web Crypto API (window.crypto.getRandomValues), which generates cryptographically secure pseudo-random values seeded from hardware entropy. Your password is generated entirely within your browser memory and is never transmitted over the internet.
What makes a password strong?+
A strong password has at least 16 characters and combines uppercase letters, lowercase letters, numbers, and symbols. The length of a password has an exponential effect on brute-force cracking resistance.
What is a memorable passphrase?+
A passphrase combines 4 or more random dictionary words separated by hyphens (e.g., 'Velvet-Falcon-Orbit-Beacon42'). Passphrases are easier for humans to remember while providing massive entropy that is extremely difficult for computer algorithms to guess.
Why avoid ambiguous characters?+
Ambiguous characters like the uppercase 'I' (India), lowercase 'l' (lima), digit '1' (one), capital 'O' (Oscar), and digit '0' (zero) often look identical in many fonts. Excluding them prevents confusing typos when transcribing passwords.
How does the QR Code transfer work?+
Click the QR icon next to your generated password to produce an on-screen QR code. Scanning this code with your mobile camera lets you instantly copy the password to your phone without having to email or text it over unencrypted channels.
