1P 8 Unlocking Multiple Vaults

@HenryY

Thank you for the reply. There are several security considerations that led us to make the changes that we did in 1Password 8:

• When someone chooses an account password they intuitively expect that only that password will be able to unlock their account. With 1Password 8 only the account password associated with a 1Password account can ever unlock the vaults stored in that 1Password account.
• Organizations often enforce password policies to make sure that their employees/members are using a password that fits their organization's security requirements. With the previous way of doing things it was possible to unlock a 1Password account with a password that didn't meet the password policy that an organization set for that organization's 1Password accounts if another 1Password account with a weaker account password was added to the app first.

There are also other considerations that we considered, especially from a usability perspective. For example, we had many reports of users who would get used to unlocking the 1Password app using the account password of one account and who would forget the account password of their other account due to lack of use and end up being locked out. By enforcing that users regularly use their specific account passwords we prevent users from forgetting their account passwords.
