Passkey as security key doesn't work on Vanguard

Hey tvandinter, it sounds like Vanguard supports 2fa with a security key. However, using a passkey in that capacity will not work. A passkey isn't a second factor, and it appears that's causing an issue on Vanguard's website.

I'm unable to create an account on Vanguard's website to test this. That said, I do recommend taking a closer look at the security key option on Vanguard's website to see if they list examples of what they accept. Additionally, if you want to do some testing, you can save a passkey for your Vanguard account in Chrome or with iCloud keychain. You can try signing in, and if you run into the same troubles, then it confirms that Vanguard does not yet support passkeys.

To store a passkey for Vanguard in iCloud keychain, please see this guide: https://support.apple.com/guide/iphone/passkeys-passwords-devices-iph82d6721b2/ios

Let us know what happens if you test that. Thanks for your time.
