You can use ID.me in both DrChrono and another system in which you have an established ID.me account. Since you already have an account with ID.me, you will not need to create a new one.
If you are already using EPCS with one DrChrono account and you need to move it to another DrChrono account, follow the steps in this article.
1. On the main login screen, do not select Create New Account. Instead, enter the SAME email and password you use for your existing account and select Sign in to ID.me, or sign in with Google, Facebook, or LinkedIn.
2. Once you have signed in, follow the instructions as described starting at step 4. If you are transferring from DUO to ID.me for EPCS you can continue from step 2 here.
