Since update I can't anymore login at once for multiple accounts

Hey @swissbird, thanks for reaching out.

I understand since installing 1Password 8 you're required to unlock each of your accounts separately. This is the expected behaviour as 1Password 8 will only unlock multiple accounts if they share the same account password. If you'd like to unlock your business and personal account at the same time, I would recommend setting the same account password for both accounts.

If you're interested in the details surrounding this change, check out this post by a member of our security team: https://1password.community/discussion/comment/608291/#Comment_608291

I hope that helps. Let me know if you have any questions!
