This information applies to both iOS and Android users. Where there are instructions, these are given in relation to iOS, but the steps are very similar in Android.
As illustrated below, with the MIRACL Trust mobile app (or via the in-browser UI), if required, you can set up more than one ID for one or more web services. For each web service you are registered with, a record is stored of the email address (identity) you use to log in. It is possible to register using more than one ID/email address against the same service (e.g. in the case of having two accounts for the same service, with different levels of access).
