Question

I was trying to implement 'Securing Django Admin login with OTP', however I can't login into the admin panel now. I removed the app from everywhere but still doesn't work. Any solution for this?

Answer 1

If you are on development version you cant use https connection on your localhost so just turn your URL to http and error will be disappear. ex:

https://localhost:8000
or
https://127.0.0.1:8000

just turn it to

http://localhost:8000
or
http://127.0.0.1:8000

also may be at 127.0.0.1:8000
