Unable to access Google Maps

If you are using your Uni Google account you may not be able to access Google Maps and some other services (possibly the error message talks about an institutional block). The root cause of this is that you have to 'opt in' to access some Google services and Maps is the main one. You can do this from a link on this UIS page. Alternatively, you can open a private browser to access Maps.

I have a new smartphone and cannot now use the MFA authenticator app

If you get a new smartphone (and no longer have access to your old one) you may not be able to  set up the authenticator app on your new phone. If so, you will need to email the UIS Service Desk <servicedesk@uis.cam.ac.uk> and ask them to reset your current MFA methods. Please note that we, Maths IT, cannot reset this for you NOR will UIS accept our instructions on your behalf. UIS will likely ask for your date of birth to help verify you so you may wish to provide this in your initial contact.

This problem can be prevented by setting up more than one MFA method.
