newauth SSO

newauth is a passwordless Single Sign-On provider that replaces passwords, SMS codes, and authenticator apps with something fundamentally different: users sign in by clicking their secret spots on images they've chosen. No typing, no second device, no codes to intercept. Under the hood it's standard OIDC + PKCE — the same protocol your existing identity stack already speaks. Drop newauth in as an identity source alongside or instead of what you run today. No migration, no rip-and-replace. How it works for users: During onboarding, users pick a secret spot on each image in a set chosen by their organisation — typically between 6 and 12. At sign-in, newauth presents a random subset of those images, different each time. Users click their spot on each one shown. The random selection means observing one sign-in doesn't reveal enough to replay it. Muscle memory does the work — sign-ins take seconds and get faster with each visit. How it works for security teams: There's no password database to breach, no SMS code to intercept, and no push prompt to fatigue-bomb. The credential is spatial and personal — it never transmits as a string, so it can't be phished the way a password can. Each user gets a pairwise pseudonymous identity per application, so cross-app tracking is structurally impossible. What's included: Image-click authentication, unlimited sign-ins, session validation and step-up authentication, per-app pairwise privacy, and consent management on all plans. Paid plans add custom domain. The free plan supports up to 50 active users with no credit card required — paid plans start at $3.00/user/mo. newauth is cloud-hosted. Pricing scales with active users: free up to 50, then $3.00/user/mo (Growth), $2.50 (Business, 2k–10k users), $2.00 (Scale, 10k–50k), and custom Enterprise above that.

Photolok

Photolok is a patented cloud-based passwordless authentication platform that utilizes enhanced steganography security techniques. It's the only login process that offers an easy and engaging user experience using photos instead of passwords. The authentication process involves three simple steps. First, enter your email address. Then, a code is sent to your phone for verification. Finally, select your pre-selected photos to gain access to your account. Photolok provides robust protection against various security threats, including hackers, bots, phishing, ransomware, keylogging, shoulder surfing, and even thermal camera biometric attacks. It accomplishes this through innovative security measures, including: The "Duress" photo acts as a silent alarm, immediately sending security alerts to designated IT and security personnel when a user is forced to enter their device against their will. The "1-Time" photo safeguards against shoulder surfing by automatically deleting it from the user's account after a single use. Additionally, a login alert is sent to the user to prevent unauthorized access attempts. Compared to traditional password logins, Photolok offers superior effectiveness. It addresses the fact that 81% of online breaches originate from compromised passwords, underscoring the importance of robust password security. By adopting passwordless authentication solutions like Photolok, users can experience enhanced security and enjoy the potential benefits of a password-free login experience.
