thanks for raising this and the PR too. The username is required for externalbrowser authentication and it's expected to fail without it. If the node.js driver somehow is able to authenticate with externalbrowser without username, that's not the expected behaviour.

Please, provide username in the connection at all times for all authentication methods. If there's a Snowflake documentation which says otherwise, I would like to know about it because I might miss something. Thank you !

I want to leave a +1 that having to specify the username is cumbersome especially when you are providing template code to others and they need to modify it before login in with externalbrowser.

@sfc-gh-dszmolka could you elaborate on the threat you are trying to close with this assertion?

@sfc-gh-dszmolka According to the Docs
https://docs.snowflake.com/en/user-guide/admin-security-fed-auth-use#label-browser-based-sso

The web browser client is supposed to be where we are prompted for credentials, hard-coding the username in the script is counterintuitive to the point of having a web browser auth

@sfc-gh-dszmolka Can we get an update on this?

hi, nothing much to update from my end - thank you for your contribution in the PR, the team will review once they get to it.
