OAuth user cap reached limit although our application already verified

[Rawit_S]

Hi,

I have a question about OAuth user cap limit. Now we face a problem when a new user want to authentications for using our service with google API that show error 

 

Then I go to checking a OAuth consent screen page I found a OAuth user cap limit is already reached to 100 user.

And I check a Unverified app documents I found that will reach limit only for application which isn't verified but my application is already verified.

How to fix a  problem or can we increase a user limit cap? If need additional information please let me know. 

Thank you.

Hi @Rawit_S,

Welcome to Google Cloud Community!

According to this documentation: 

---

To protect users and Google systems from abuse, apps that use OAuth and Cloud Identity have certain quota restrictions based on the risk level of the OAuth scopes an app uses.

---

You're encountering the "This app is blocked" error when new users try to authenticate with your Google API service. This is happening because your OAuth user cap of 100 has been reached. 

There are generally two ways to address this user cap once reached:

1. Request an Increase:

You need to formally request that Google increase your user cap. This involves explaining the reasons for needing higher limits and demonstrating the legitimacy of your application. Fill out the request form with details about your app, its use case, and why you need the larger cap. Be as thorough and convincing as possible.

2. Adjust Scope Requirements:

If your app doesn't absolutely need all the sensitive or restricted scopes that you're currently requesting, then reducing your access requests could allow your app to stay within a smaller cap. However, this isn't always possible, and might not even be desired.
