# Start Fresh With a Brand New Data File (Agile Keychain)

If you need or want to start over with a blank 1Password data file (called a keychain), you can do so easily:

- Quit 1Password and all running web browsers.

- Use Finder to locate your data file. You can find the location of your data file by looking in the 1Password > Preferences > General window.

  If you cannot open 1Password’s Preferences window, try this default locations to find your 1Password data file:

  - Home > Library > Application Support > 1Password > 1Password.agilekeychain

- Rename the data file to something else. For example, you could add “_old” to the file name. You could simply delete the file, but to be safe it is best to rename it and then delete the renamed file once you get everything working.

- Start 1Password and follow the setup instructions. A new data file will be created for you automatically after you provide the Master Password you want to use.
