Multiple PSN Accounts on the Same Vita Memory Card
UPDATE 8/28: I cannot confirm this independently, as the 1.80 update has killed my Vita, but online reports indicate that as of firmware 1.80, you can no longer have multiple PSN accounts' data residing on the same memory card. What follows is only valid on firmwares prior to 1.80.
Contrary to certain reports, it is possible to use multiple PSN accounts on the same Vita memory card. In fact, it is quicker to switch accounts with one memory card than two, as you only need to reboot once instead of three times.
- Games and apps obtained from the PS Store off different accounts can live on the same memory card. However, you will get an error when trying to launch them off any account other than the one it was purchased on.
- Saves for physical copies of games are bound to the PSN account you first played the game on. Any PSN features, such as trophies, will be disabled if you play a game on the wrong account. You can however play and progress in the game just as if you didn't have a PSN account configured on the device in the first place.
- You must be online when switching accounts. There is no known way to switch PSN accounts while offline, regardless of whether you have one memory card shared across several accounts or one memory card per account.
Steps to Follow
- Launch the Trophies app to ensure your trophies are synced with the PSN server.
- Go to Settings → Format → Restore the PS Vita System.
- You will be asked if you want to deactivate the system from the current PSN account. Say Yes.
- You will be asked if you want to restore the settings to default values. Say Yes.
- You will be asked if you want to format the memory card. Say No.
- The Vita will reboot and take you through the initial setup process. From there, you can log into your other PSN account. You will sadly have to endure the long, unskippable intro video.
Since you are restoring everything on the Vita's internal memory to default values, Wi-Fi network passwords and home screen arrangement will be lost, among other things. You may want to group content obtained on or bound to other accounts on home screens with a different background to avoid confusion.
