Authenticate advertisers in the initial advertising settings

We are sometimes asked to authenticate advertisers on Google's side in the new ad setting for a new account.

I've checked some recent posts and they say Google is suspending you if you don't authenticate advertisers on your new account, and I'm wondering if this is true.

Also, I wonder if the act of authenticating advertisers under the same name will cause problems if I run multiple Google ads. (Unlike Google membership, unlimited authentication is possible.)
