The ArDrive app is the easiest & most intuitive way to use & access Arweave's permaweb, but there are times when you may want to access your data on another device. Enter ArDrive Mobile. This guide will show you how to transfer your Arweave wallet JSON file from your computer onto your phone.
(The examples used are from MacOS)
First, to start, please go to your desktop folder containing your wallet's JSON files and select both files, and click the share button in the upper-right corner.
2. Have your iPhone’s home screen unlocked, and will be able to select it on the computer to start the AirDrop.
3. On your phone, choose Open With Files and save JSONs in the downloads folder, and don’t forget to tap save in the upper right-hand corner to finish the AirDrop.
4. Go back to the home screen, and tap on the Ardrive app on your iPhone.
5. Select the wallet you want to log in with and enjoy the permaweb.
To delete your wallet JSON from your device, go back to Files, press and hold the JSON, and delete it. ArDrive Mobile securely stores the JSON in an encrypted area on your phone so nobody else can access it and allowing you to remain logged in.
