Username-Password Flow Disabled Developer Sandbox

Hello,  

 

I am trying to create an agent outside of Salesforce and connecting to a developer sandbox, however I keep receiving this error Username-Password Flow Disabled in the login history. I have enabled Allow OAuth Username-Password Flows from OAuth and OpenID Connect Settings and looked at the posts related to this, I cannot open a support case as it is not supported in developer sandbox, is anyone able to help with this?  

 

Thank you in advance,  

Avni

    Hi @Avni Patel

     

     

    External Apps don't support OAuth Username-Password Flow, since it is not a secure way of connecting as it exposes the username and password over the connection. However, If you are keen on using this flow then create a Connected App instead of External App.  

     

    If you are not seeing the option of "Create a Connected App" in App Manager, it might be disabled.  

     

    You can enable by following the below steps: 

     

    From

    Setup in Lightning Experience, in the Quick Find box(Setup Home), enter External Client Apps, and then select Settings. Turn on Allow creation of connected apps

    . 

    Here you'd get the option to create a connected app as well. The rest of the steps remain the same as you have followed to create the External App.
