1 Password desktop application wont open with the correct password

Hi @ups3270!

Do you by chance have a Primary vault in the 1Password for Mac app? The way 1Password unlocks is:

• If a Primary vault exists, then it unlocks using the Master Password for that vault, regardless of what, if any, memberships are signed in
• If a single 1Password membership is signed in, then it unlocks using the Master Password for that membership account
• If multiple memberships are signed in, then it unlocks using the Master Password of the first added membership

If you are using a 1Password membership we generally recommend removing the Primary vault. From what you are describing, it sounds like this is what could be causing the difference.
