when you migrate your primal to their new setup, which i did a few days ago and it's just a couple taps of a button an really easy, then you'll get 12 words that you can use as a backup. you could take these and import them into Agora if you'd like, and use the same wallet in both apps. you could also setup NWC if you prefer to use that too. you're going to eventually have to migrate Primal's wallet from their Strike backend to the new Breez Spark SDK powered one.
