any way to put 1password on an external drive

Hello stretch1a,

Thanks for your message. Could you please explain your use case such as changing the install location of 1Password or are you referring to your 1Password data and using this as a form of backup?

In the case of a backup, we handle that for you through 1Password.com (or .ca/.eu). In case you lose access to your account, we have the Emergency Kit that you can use to store your 1Password account credentials. The emergency kit can be printed and stored in a safe place or downloaded and saved and encrypted on external drive. I've included a 1Password blog post below: Where to Store Your 1Password Emergency Kit

If you have other questions or a different use case, please let us know and we'd happy to help further.
