I have several profiles for logging into HMRC's Government Gateway to access my HMRC services. I can log in with my Username and Password but when I enter the Access Code (sent to my mobile) the website goes back to the login page, it won't let me in. If I do the same on Microsoft Edge, there is no issue and I can login without any problems. I tried the 'Forget about this website' fix and also cleared the cache in Firefox. I will not delete all my cookies as they are vital for all my access to financial and government website access. Some profiles (different Username) will let me in (for certain Government Services) but others won't. It is not an issue with HMRC as Microsoft Edge seems to work. Can anyone provide a solution to this issue or have also experienced this issue? Thanks. René
