Message: User prompt of type promptUserAndPass is not supported

Question

I am creating Python script for a website involving pop up sign in.

Tried the below code and getting an error message

 alert = driver.switch_to.alert
 alert.send_keys('username')

Error - Message: User prompt of type promptUserAndPass is not supported

How to resolve this error? any other way to input credentials for the pop up sign in?

It sounds like it's requiring Basic auth. Instead of trying to interact with the prompt, you can just include it in the URL like `https://username:password@host.example.com/` and that works the same way as typing it in the basic auth prompt. — sytech, Mar 14 '23 at 19:11
Thanks, but it is not working. Also username includes Domain as well. — Arunkumar, Mar 15 '23 at 14:47

This is caused by lack of implementation in the driver for basic auth prompt.

Driver implementation has been blocked by a gap in the standards (see here for info https://github.com/w3c/webdriver/issues/385)

As per a comment, there are other ways to send basic auth details.

In URL: https://{username}:{password}@host.example.com/ (if you have a domain in username, then include this e.g. name@domain.com:password@host.example.com
In Header: "Authorization: Basic {String}" (Where {String} is Base64 encoded "{username}:{password}")

(Both possible using requests library which is present in AppDynamics Synthetics by default)

(Make sure you use URL Encoding if using the URL method.
