FAQ
Are these passwords safe?
Randomness comes from the Web Crypto API and generation is local — nothing is sent anywhere. Store them in a password manager, not a text file.
How long should a password be?
16+ characters with all character classes withstands modern brute force; 20+ for master passwords.
What is fake test data for?
Fill forms, seed databases and demo UIs without putting real personal data into test environments.
