Customer Login From Custom app

[sanjogkarki947]

I have a custom SMS service app where I'm implementing customer login using OTP. Customers only need to enter their phone number. I've added an OTP popup using a theme extension, and it's working correctly. Now, I want customers to log in without a username and password once the OTP is verified, from custom app.

Is there a way to facilitate customer login from custom app?
