PS Vita – Switching linked account?

I just received my PS Vita, and I found out that only one account can be linked to it.
I have been looking for a solution and I was wondering if the factory reset is the only possible way on how to switch the account.
Thanks in advance!

Answer #3
“Sony has now clarified, explaining that each account will be bonded to a memory card, not a system.
Players who want to use multiple accounts will have the option of doing so, but each account will need to be bonded to its own card. A factory reset is only required if you want to use multiple accounts but only have one memory card.
“Your PSN ID is bonded to your memory card and your memory card is bonded to your Vita,” said Sony associate brand marketing manager Crystal MacKenzie. “So if you wanted to change different PSN users but use the same memory card, you would need to go factory reset.” ”
