​A SLAC windows computing account will automatically deactivate if it is not used. A user needs to login at least once every two months. We recommend that you login once a month so there is little risk of the account getting deactivated.

Please let me know if you have any questions. 

"Log in" means to a SLAC managed machine. If you are offsite, this will be a remote desktop. There is a remote workers toolkit here and Linux server information here. Also, you could just login to your Office365 webmail​ if you have a windows email account. You can login to the web browser. (Note though that if you have a unix mailbox or just have a forwarding SLAC email in place, then you will not have access to Office365). 

It will also automatically deactivate if the cyber security training is out of date. The cybersecurity training needs to be taken every year. If you don't have a SLAC email address you may not get notification of this. You should be able to check the training status in the user portal though.

Finally, you also need to change your passwords every 6 months.
