TIP: You can change display language on the Mac without altering system language
Just found out that you can change the display language of 1Password Desktop on the Mac by going into Settings >> Languages & Regions >> App tab. Add 1Password and select the language you want. This way the system language won't be affected.
See Apple support doc: https://support.apple.com/guide/mac-help/change-language-region-apps-preferences-mac-mchlddb13d65/10.15/mac/10.15
