Do I have to uninstall 1Password7 for 1Password8 to work?

@TucsonTom2

If you are already using a membership then yes that will happen. All you'll need to do is sign into 1Password 8. If you've not previously used a membership you'll use the option to migrate your data to a membership.

Assuming membership in use: You can help by making sure all of your data is available on https://my.1password.com and ensure you have a copy of your 🚒 Emergency Kit
