Great extension, it trigger the mobile app to allow the OTP to be copied in the field on the website instead of having to write it yourself. To all people complains that the extension triggers the mobile app to copy the code. YES, it's how you don't get hacked by easily let anyone access your OTP on your computer *facepalm* If it bother you, you missed the purpose of 2FA/MFA. Continue writing your passwor on a post-it and put it on your screen edge.
