Authentication is the front door of your application. Get it wrong and everything behind it — payments, personal data, admin tools — is exposed.

Never roll your own crypto

Use battle-tested libraries and identity providers for password hashing, token generation, and session management.

Hash passwords properly

Store only slow, salted hashes — never reversible encryption of passwords. Modern algorithms adapt to increasing hardware power.

Secure session handling

Use HTTP-only, secure cookies where appropriate. Regenerate session IDs on login. Expire idle sessions.

Offer multi-factor authentication

TOTP apps or SMS second factors dramatically reduce account takeover. Make MFA available at least for admin and high-value accounts.

OAuth and social login wisely

Google or Facebook login improves conversion, but link accounts carefully and still verify email ownership for critical actions.

Rate-limit and lockout thoughtfully

Throttle failed login attempts to block brute force without enabling denial-of-service against legitimate users.

Password reset done right

Single-use tokens, short expiry, no account enumeration in error messages, and notification when passwords change.

The takeaway

Use proven libraries, hash passwords correctly, secure sessions, add MFA, and implement careful reset flows — authentication done right is mostly discipline.
