When I attempt to enable two-factor authentication for my staff account "DPatrick (WMF)", the QR code cannot be read by Google Authenticator. Testing indicates that this is because the [[https://github.com/google/google-authenticator/wiki/Key-Uri-Format|label]] portion of the key URI is not URI encoded.
# In Firefox, with Firebug installed, login to https://meta.wikimedia.org/ as a WMF staff person.
# Navigate to https://meta.wikimedia.org/w/index.php?title=Special:OATH&returnto=Special%3APreferences.
# Scan the QR code in Google Authenticator and observe that an error is displayed.
# In the Firebug console, enter the following:
`$("#qrcode").qrcode("otpauth://totp/" + encodeURI("Meta:YourAccount (WMF)") + "?secret=YOURLISTEDSECRET");`
# Scan the QR code in Google Authenticator and observe that the entry is successfully created.
