How many onlykeys needed for 4 devices

DEAR PEOPLE,

I HAVE THREE PCs AND ONE ANDROID, FOUR DEVICES.

DOES ONE ONLYKEY COVER ALL OR DO I NEED FOUR ONLYKEYS?

HARD FOR ME TO BELIEVE NO ONE HAS ANSWERED THIS OR ASKED IT.

MAYBE IT IS HIDDEN IN DOCS?

THANKS,

JOE

You would need one onlykey

Like almost all security tokens it can be used on a unlimited amount of devices, the only issue you may have with a security token is whether or not it supports the operating system you require to use it on.

On a side note certain features require the app being open to for them to function like OTP so this can also restrict the devices you can use it on as you would only be able to use it on devices that can run the app.
