Thread:Support/Two Factor Authentication English messages not imported

FuzzyBot didn't import English (and maybe documentation) messages for Two Factor Authentication extension. Without these messages, msg-mw templates using TFA messages as argument wouldn't work. I created MediaWiki:Twofactorauth-scratchwarning-text/en and MediaWiki:Twofactorauth-scratchwarning-link/en because they are used in documentation.
