My phone has been stolen so I was wondering if I could change my password / remove the account form my phone?
Hey @yas, drop us an email to feedback@getmondo.co.uk and we’ll get it sorted for you 
You can’t do this yourself at the moment I’m afraid!

If you are lucky enough to have had find my iphone switched on (the apple setup wizard badgers you to do so these days) you can locate/lock/wipe the whole device which will take effect if the device gets connected to the Internet (which they’d have to do to use the Mondo app anyway).
