Chrome 80 appears on February 4 complete with “SameSite” updates to close off the potential for cross-site request forgery attacks. Office 365 has many web interfaces, so Microsoft has had to do some work to prepare for Chrome 80. Microsoft says that Office 365 is prepared but customers will have to apply patches for on-premises products, once the patches are available. Or stop using Chrome. Which mightn’t be a bad thing.
