"This browser or app may not be secure."

AuthService.RequestAuthorizationCode opens a new tab to Google's OAuth workflow. I am not greeted with a list of Google accounts I've signed into with this browser (should be 3 in my case), rather I must supply the email address manually. Upon entry and submitting the single-input form, I am greeted with:

Couldn’t sign you in
This browser or app may not be secure.
Try using a different browser. If you’re already using a supported browser, you can try again to sign in.

CodeBeam.GoogleApis.Blazor 0.2.1.1
Edge 102.0.1245.44 and Chrome 102.0.5005.115

The above issue is present when using the Chrome/Edge browser instance launched by my IDE (Rider). I found that I can successfully authenticate with Google by launching my app from an existing browser instance (not owned by the IDE). Likewise, I can authenticate using Chrome or Edge from VSCode rather than Rider. This leads me to believe it's something about how Rider is using the browser. For fun, I took a look at the application processes in Task Manager and found their command line flags:

Via Rider:

--display-capture-permissions-policy-allowed --remote-debugging-port=0 --lang=en-US --device-scale-factor=1 --num-raster-threads=4 --enable-main-frame-before-activation --render-client=8 --launch-time-ticks=16669587895 --mojo-platform-channel-handle=5634 --field-trial-handle=1684,i,14254804435355302897,17644990483725602622,131072 /prefetch:1

Via VSCode:

--disable-client-side-phishing-detection --display-capture-permissions-policy-allowed --disable-background-timer-throttling --disable-breakpad --remote-debugging-port=0 --lang=en-US --device-scale-factor=1 --num-raster-threads=4 --enable-main-frame-before-activation --render-client=12 --launch-time-ticks=13213642566 --mojo-platform-channel-handle=6684 --field-trial-handle=1804,i,17342343993749335918,16033479073627220906,131072 /prefetch:1

I took the command line flags used by VSCode and set them explicitly into Rider's settings, then verified in Task Manager that the custom flags were used as desired, to mimic VSCode. This didn't work.

Clearly my issue is not within the scope of this project. Closing! I'll update here later for anyone who might stumble into this.
