Advanced security

SOC 2 Type 2 certified and CCPA compliant, with third-party audits and penetration tests every quarter.

Magic links

Lift sign-up conversion and filter out spam sign-ups with single-use magic links.

Session management

Sentrel handles the full session lifecycle, including active device monitoring and one-click session revocation.

Social sign-on

Add high-conversion social sign-on to your app in an afternoon. 24 providers, and the list keeps growing.

The best practices baked into their <SignIn/> and <UserProfile/> components would have taken us three quarters to build in-house, and we gave up nothing on enterprise extensibility or brand customization.

Sentrel’s integration gives Rowanbase developers another genuinely good option for handling authentication. And the team behind it is a pleasure to work with.

Sentrel feels like the first time I booted a machine off an SSD. It is so much faster and simpler that it changed the way I start projects.

Sentrel let us spin up a new product in hours instead of weeks. For a company that cares this much about developer velocity, it was exactly what we needed.

We shipped MFA, SSO, and SAML for our customers in a fraction of the time. Security improved and we cleared the must-haves for enterprise prospects.

After spending far too many hours on auth problems that looked simple and were not, we moved to Sentrel and the whole burden lifted. We only wish we had done it sooner.
