Garbage, bordering on "Account Lockout Scam". Was forced to use Google Auth for a crypto site. There was no way to "copy" the secret key, and was not instructed to do so. Creates a scenario where I can't recover my acct. Do Not Use Google Authenticator Unless You Write Down And Verify Your Secret Keys For Each Service. Completely Screwed If Lost Account. And Google Ignores This Significant Security Nightmare.
