Error! Client authentication is required

Hi @glen.little,

Welcome to the Community!

It sounds like you may be running into an issue that is addressed in the following thread:

Passwordless connection not working for tenants created after Jan 2, 2020

Hi @cyrilchapon, @j1315b, @codescribblr There’s currently a bug that does not let you TRY the passwordless connection for Regular Web Apps if the tenant has the “Enforce client authentication for passwordless connections” field enabled. This is because the call to /passwordless/start that is made from the TRY button dos not include the client secret. New tenants always have that property enabled, and you can’t turn it off, as it’s a security risk. You should not make calls on behalf of confide…

Can you take a look and see if it solves your issue?

Thanks,
Dan
