Entra Shared Device Mode and iPad

Copper Contributor



I am having problems logging into Microsoft 365 apps (Word, Excel, PowerPoint) when I have my iPad in Entra Shared Device mode. When I open one of these apps I receive a prompt to sign-in, and when I start to enter my credentials it crashes. MS Authenticator shows the device is set as a multi-user device. Other applications such as Teams, Outlook, and OneDrive work great as once I sign-in to one I'm auto signed-in to the others. It's just these three apps that are not getting the SSO extension...


This is what the crash report shows: 


uncaught ObjC exception, reason: -[MALAuthenticatorImpl readAllAccounts:]: unrecognized selector sent to instance 0x3013a3830


Do the above 365 apps work for anyone else in Entra Shared Device mode? Maybe I misconfigured something? Thank you for any help with this.
