Is there a supported way of launching Google Authenticator on Android?
I found that it's easier to import the secret key by the web link on iOS.
such as:
<a href="otpauth://totp/TEST:TEST@gmail.com?algorithm=SHA1&digits=6&issuer=TEST&period=30&secret=ZNSXZIM4GZDP25LCHFC4QVRLVLBNJHU3" target="_blank">click here on iOS</a>
