When I attempted to sign into Windows 10 on my PC Specialist laptop, the password box had changed to PIN and would only type numbers. When I typed the numbers without the letters another small screen appeared suggesting other options, one of which was to sign in with my Microsoft password which didn't work. But when I put my Windows password in, all was well. If I go into settings, sign in options it appears I can change sign in back to what I had before. Are there any pitfalls in doing this?
