You can deploy a `whoami` canister. You’ll know you’re successful if you can log in with II, check your principal, log out, and then log in a second time, getting the same principal back.

Thank you all for your help and insights. For anyone who might be looking for the end solution, based on what everyone said here, I created this proxy page:

[functionland/Web-Identity-Providers: This is a proxy that can be used to connect applications to Internet Identity by Dfinity. (github.com)](https://github.com/functionland/Web-Identity-Providers)

main code here:  
[Web-Identity-Providers/source/src at main · functionland/Web-Identity-Providers (github.com)](https://github.com/functionland/Web-Identity-Providers/tree/main/source/src)

And used it here:  
[photos/auth.ts at main · functionland/photos (github.com)](https://github.com/functionland/photos/blob/main/components/Auth/auth.ts)  
line 15 to 22
