Created a Bot Service on Azure and in 'configuration' it keeps adding Application Insights key on its own

In Bot Service -> my Azure Bot -> Settings -> Configuration, i see two errors due to 'Application Insights Instrumentation Key' and "Application Insights API key" about the value not being GUID or 40 characters long.

I would remove it but it would just automatically get added back in. For the first key, it keeps using my username (******@outlook.com). I don't see the two fields being required so this is really confusing.

    Hi @IamTypingNow

    The fact that your own outlook.com address shows up in the Instrumentation key field is the giveaway. That's almost certainly your browser's password manager autofilling the form, not Azure. Browsers often treat a "key" field next to a password-style field as a login form and drop your saved username and password into them. Azure then complains because those values aren't valid keys.

    All three Application Insights fields on the Configuration page are optional, so you can leave them empty:

    1. Open the Configuration page in an InPrivate or Incognito window, where saved logins don't autofill.
    2. Clear the Application Insights Instrumentation key and API key fields completely.
    3. Select Apply and reload the page to confirm they stay empty.
    4. If you want to keep using your normal window, remove the saved password for portal.azure.com in your browser's password settings, or turn off autofill for that site.

    If you later want bot telemetry, paste the real values from your Application Insights resource instead of typing them.

    Does the problem come back if you open the page in a private window?

    If this resolved your issue, please consider accepting it as the answer. If the fields still fill themselves in, let me know and I'll be happy to keep helping.
