After using 1Password for a long time, I plan to go back to Enpass, the first password manager I used. This is mainly because multiple vaults are available in the latest Enpass versions.
My 1Password account is secured with a master password, secret key and 2FA. At Enpass I will have to use a keyfile to make the vault just as safe.
But where can I store my keyfile the best and easiest so that I can access it on any device (Windows, Android smartphone, Chromebook)?
