I have a couple of encrypted USB drives that I use with my MB Pro, running High Sierra. When I have inserted either drive into a USB port it always has prompted for a password except yesterday I was quite surprised when one of the drives just opened without any prompting. The other drive did prompt, as expected.
Now I suppose there's a very small chance that the last time I used it I inadvertently checked the option to add the password to Keychain but I would be very surprised if that's what I did as in all my years of using Macs I never have knowingly used it. I went into Keychain and removed the drive from the list and now it again prompts for a password. I was just wondering if there is any other explanation. Has anyone else ever experienced this?
