Developers must never store passwords in plain text. Secure systems use hashing and salting (like bcrypt) to transform passwords into unreadable strings [23].
Once verified, the application maintains your status through Cookies (stored in the browser) or Tokens (like JWTs), allowing you to stay logged in as you navigate [12, 14]. 2. Modern "Zero-Typing" UX Trends
An extra layer—like a code sent via SMS or generated by an app—ensures that even if a password is stolen, the account remains safe [26, 30].
With over 80% of breaches linked to weak credentials, "Sign in" now often requires more than just a password [23].
Modern design focuses on reducing "friction"—anything that makes it harder for a user to get inside.
