One of my computer clients has been writing a daily blog for many years. They post it to Facebook around midnight and it has around 1000 followers. Last year Facebook increased his security requirements and occasionally wants proof it’s really them. Facebook had directions for using a smartphone for authentication. My client doesn’t use a smartphone and this would have made it easier to authenticate them. We had to order a fingerprint reader which connects to the USB port and occasionally they must use it to authenticate.
This time I don’t know what exactly happened, but when I arrived Facebook wanted my client to change their password. I got around this requirement by entering their FB PIN and having them press their index finger on the reader. They got in to Facebook and started entering yesterday’s blog .
