A Masterclass in Insecure Authentication Design
Description
A two-panel meme format used to express sarcasm about poor programming. The top panel displays a web UI for account creation. The form has fields for username, password, and password verification. The username 'alabaster1996' is shown with a green checkmark, indicating it's available. However, the password field is marked with a red error message that reads: 'password is taken by Hanklu6 suggested: Jmpr123 Jmpr121 12Jmpr1'. The bottom panel features a still image of a battle-damaged, weary-looking Terminator (Arnold Schwarzenegger) from what appears to be a video game. Below him is the caption, 'Superior programming.' The humor is derived from the absurd and fundamentally insecure logic of a system where a password can be 'taken' by another user, implying passwords are not hashed and are unique across the entire user base. The sarcastic caption highlights the frustration developers feel when encountering such poorly designed systems

This isn't a bug; it's a revolutionary new global singleton password constraint. It's part of their strategy to achieve stateless authentication by having every user log in with the same password
Nothing says “defense in depth” like comparing your new password against the global plaintext table - credential stuffing as a service
When you implement bcrypt with a cost factor of 12, enforce 2FA, and rate-limit login attempts, but your entire security model collapses because someone's password is literally "Jmpr123" and they're genuinely surprised it's already taken
When your authentication system integrates HaveIBeenPwned's API so thoroughly that it literally tells users 'Sorry, HankIu6 from the 2019 breach already claimed that password' - that's not just defense in depth, that's having a T-800 guarding your credential database. Sure, it creates UX friction, but at least your users won't be the low-hanging fruit in the next credential stuffing attack. Though explaining to stakeholders why registration completion rates dropped 15% because we're 'too secure' is its own special kind of product management hell
If your form reports 'password is taken by Hanklu6,' you didn’t build auth - you put a UNIQUE index on plaintext and turned OWASP A02 into a feature
Signup says “password already taken” - aka a UNIQUE INDEX on passwords; congrats, your auth UX doubles as a dictionary attack and OWASP is already writing the incident report
Scaled monoliths to Kubernetes, but Levenshtein distance in auth.js claims his first victim
