Problem getting onto computer

[MickyTeddy]

Yesterday all of a sudden I was asked to enter my password to get into my account. I am the only user of my MacBook Air and as have arthritis it is a tad annoying. I have gone to users and accounts and unlocked the padlock and unticked the user and then relocked the padlock. But it is still asking for password to access the computer. I have been a Mac user for over 27 years and have never experienced this before. Any ideas please?

The recent security update seems to mess with this.

In Users and Groups, check Login Options and see if Automatic login is enabled. If it is, turn it off, logout and in again, then go in and turn it on again.
