You can add a second email address to your profile, this is relatively simple. Log in to the registry, click your name at the top right and go to Profile. Click Add email Address to add a second email.
But if you want to change the email you use to login to the registry, this takes several steps. The steps depend on whether you were using Google to authenticate your existing address or not. It would be good to go through this process before you close your first email account.
Using Google authentication
Log onto https://registry.paratext.org. Click your name at the top right. Now click Settings. At the top you will see identities. You should see your existing email address listed with the Google logo. If your new email is also based on Google, click “Change”. Your browser will bring up the list of Google accounts it knows about, you pick the one you want. If the one you want is not in the list, click “Use another account”. If Google asks you to login to the other account, or to give permission for registry.paratext.org to access your info, click Yes. When this is finished, you should now see your new address in the Google section of Identities, and you can now start using your new email to login to the registry.
If your new email is not based on Google (or you don’t want to use Google authentication), click “Remove” in the identity line. It will ask you to enter your new address, then send you a link to the new email. Go to your Inbox and click the link. Now the registry will ask for a login password. This does not have to be the same as your email password. When you set the password you should be able to login using your new email and your new password.
Not using Google authentication
Log onto https://registry.paratext.org. Click your name at the top right. Now click Profile. Click Add New Email and put in your new email address. The registry will send an email with a link you must click to verify your email. Go to your email and click on the link in the message. Now, when you come back to the Registry, you can click on your name, go to Profile, and each email address on your profile should have a trash can by it. Click the trash can by your first email to discard it.
The password you set up to login to the registry is not changed when you change your email. You can log on to the registry using the new email and your existing password. If you want to change your password for the Paratext registry, click on your name at top right and go to Settings. There is a section called Password where you can change your password.
If your new email is based on Google, you can use the Google authentication method if you wish, where you login to your Google account in the browser, and Google tells the Paratext registry that you are you. Click the link for the Google authentication method in the Password section of Settings. Google will ask if you give permission for registry.paratext.org to access some of your account information, and if you grant access, you can then use the Google authentication to login to the registry.
If you no longer have access to your first email
You still may be able to login to the registry if you were not using Google authentication. You can enter your old email and the password you set up for the registry, then proceed to change your email. If you used Google authentication, or if you have forgotten your registry password, you will have to have help to get your new email address into the system.
