Passport password issues


This is my first post as I am having a problem with my WD Passport. I had been using it for approx. a year on my Mac Pro computer with no problem.

I attempted backed up today on my laptop after having not backed up for 90+ days. This time I tried to use the Passport it started asking for a password. I never put a password in, and I cant understand what is happening much to my frustration.

Is there a default password? It keeps asking for the “Keychain” password to access the device.

If anyone has a similar problem I would be interested in hearing from you,
