Authentication Is the Front Door to Everything
Every digital system has users. Every system with users needs to verify who those users are before granting access to their data, their accounts, their resources. Authentication is that verification — the moment a system answers the question "are you really who you say you are?" How that question is answered determines whether accounts stay secure or get compromised.
auth.mom explores authentication from every angle: the cryptographic foundations that make it secure, the protocols that make it interoperable, the UX patterns that make it usable, and the operational practices that keep it reliable.
The Authentication Spectrum
Not all authentication methods are equal. Here is the security spectrum from weakest to strongest:
Each method higher on the spectrum provides stronger phishing resistance and credential security
The Authentication Landscape
Passkeys (FIDO2/WebAuthn)
Phishing-resistant, device-bound cryptographic credentials. The future of consumer authentication.
Authenticator Apps (TOTP)
Time-based one-time passwords. A substantial upgrade from SMS, works offline.
Hardware Security Keys
Physical devices like YubiKey. Strongest protection for high-value accounts.
OAuth 2.0 and OIDC
Federated authentication — log in with Google, Apple, or GitHub through open standards.
Magic Links / Email OTP
Passwordless flows that trade cryptographic strength for simplicity.
Push Notifications
Approve on your phone. Modern implementations include number matching to defeat fatigue attacks.
For Developers and Security Teams
If you are building authentication systems, every design decision has security implications. The choice of token format, the length of session lifetimes, the revocation strategy, the account recovery flows — all of these matter. auth.mom digs into these decisions with the specificity that practitioners need.
