Unable to Enable OAuth Username-Password Flow in Developer Org (Winter ’26) – “Username-Password Flow Disabled” in Login History

Hello everyone,

I am trying to integrate an external system using OAuth 2.0

 from Postman. 

 However, I am facing the following issues in my 

Developer Edition org (created from developer.salesforce.com

): 

 

What I have done:

  1. Created a Connected App
  2. Enabled OAuth Settings
  3. Added Callback URL
  4. Enabled all required OAuth scopes
  5. Used Postman to call:     https://login.salesforce.com/services/oauth2/token
  6. Added: grant_type=password, username, password+securityToken, client_id, client_secret         Issue:    When I check Setup → Login History, the failure reason says:  “Username-Password Flow Disabled” 
  7. But inside my Connected App → OAuth settings, I cannot find the option:
  8. I also don’t see any option related to OAuth username-password flow or Secure OAuth Client Authentication.
