This is wonderful news. I recently convinced my wife to update her 1Password app so we could get use the family plan and share vaults, and also because I thought it would be a good idea to have the latest version. She upgraded to 1Password 8, deleted 1Password 7...and it was only then we realized she couldn't use her PIN to unlock the app anymore. She is morally opposed to using biometrics to unlock her devices, so using a PIN is her first and only preference. If not for this blog post stating the PIN update is coming, a divorce may have been in my future. So thanks for saving my marriage!
