We ranked 13 authentication providers by real-world reliability over the last 90 days, using 89 status page incidents and our own around-the-clock uptime checks. An authentication provider sits in front of every login, sign-up and password reset in your app, so when it fails nobody can get in, even if the rest of your product is running normally. Customers who are locked out stop buying and start emailing support, and staff can lose access to internal tools that use the same single sign-on. Because sessions and tokens are checked on many requests, a slow or erroring identity service can also degrade an app for users who are already logged in.
Most reliable authentication provider:Ory Network (score 96.4/100). Highest uptime: Ory Network (99.99%). Fewest incidents: Ory Network (3 in 90 days). Fastest to resolve: Ory Network (avg 16m).

Authentication Providers reliability at a glance
Across the 8 ranked authentication providers, average 90-day uptime is 98.24%. Reliability scores range from 96.4 (Ory Network) to 28.7 (Supabase Auth).

The typical vendor takes 3h 18m to resolve an incident. Ory Network is fastest, at 16m on average.
Supabase Auth reported the most incidents (39 in 90 days).
What to check before you choose a authentication provider
Find out which region your tenant runs in and read the incident history for that region, since many identity outages hit one data region.
Separate incidents in the login and token APIs, which lock users out, from dashboard, analytics or webhook incidents, which only slow your team down.
Check how sessions behave during an outage: apps that validate tokens locally keep logged-in users working, while apps that call the provider on every request fail with it.
Look at email and SMS delivery history too, because one-time codes and magic links depend on third-party senders and fail more often than the core API.

Each bar is one day. Hover a bar for that day's uptime and incidents.
These vendors join the ranking once we have enough evidence: at least 14 days of data, and for vendors with a quiet status page (silent for a year, or for 90 days while their competitors report several incidents), 30 days of our own independent monitoring.

What is the most reliable authentication provider?
Based on the last 90 days of data, Ory Network is the most reliable authentication provider we track, with a reliability score of 96.4/100 and 99.99% uptime.
How do you measure authentication provider reliability?
We poll each vendor's public status page every few minutes, record every incident, and run our own uptime checks against each vendor's login and customer-facing pages. Uptime (40%), incident frequency (20%), average time to resolve (20%) and transparency (20%) combine into one score out of 100.
How often are these rankings updated?
Continuously. Status pages and uptime checks run every five minutes and scores are recalculated several times an hour.
Can vendors pay to rank higher?
No. Sponsored placements are clearly labelled, shown separately from the rankings and never change a vendor's score.
