How can I move my ID to a new device?

When you switch your device or reset it to factory settings, you can transfer your Threema ID and use the app as usual. To transfer your ID, you need an ID backup. A data backup contains your ID, but it can only be used on the same operating system. For this reason, it’s recommended that you create an ID backup by following the instructions below. Please note that an ID backup doesn’t contain chats, media and your contacts' green verification levels. You can always export chats.

1. Backup your ID

Android

  • To create a backup, select the menu in the upper left and then tap on “My Backup”. Select the option “ID Backup” and choose a password. Make sure to memorize this password; without it, you will not be able to restore your ID.
  • Your ID data (consisting of your private key) will be encrypted and shown to you as a text string and QR code.
  • Save the backup of your Threema ID in a secure location. You can also send the information to yourself by email.
  • You can include your ID backup automatically in your Android Backup.

iOS

  • To create a backup, tap on “My ID” in the app, navigate to “Backup”, and choose a password. Make sure to memorize this password; without it, you will not be able to restore your ID.
  • Your ID data (consisting of your private key) will be encrypted and shown to you as a text string and QR code.
  • Save the backup of your Threema ID in a secure location. You can also send the information to yourself by email.
  • You can include your ID backup automatically in the next iTunes/iCloud Backup.

Windows Phone

  • To create an ID backup, navigate to “Settings” and select “Backup”.
  • Choose how to save your backup: on OneDrive, as text code or as QR code.
  • Tap “Backup your Threema ID” and choose a password. Make sure to memorize this password; without it, you will not be able to restore your ID.
  • Your ID data (i.e., your private key) is now encrypted and saved on OneDrive or displayed as text string or QR code.

2. Restore ID from Backup

  • When starting Threema for the first time, select “Restore from backup” and follow the on-screen instructions.
  • If Threema is already set up with another ID which you would like to replace, remove the current ID first:
    • Android: In the sidebar, tap on your ID, then select “Delete ID”.
    • iOS: In the tab bar, tap on “My ID”, then select “Delete ID”.
    • Windows Phone: In the “My ID” tab, select “Delete ID”.
    Please note: The ID will be deleted only on the current device; if it is set up on another device, it will not be deleted there. Also, the deleted ID can still be restored using an ID backup.After deleting the ID, you can restore an ID as you would when starting Threema for the first time (see above).
