Q. Can I register more than one MFA device? Yes. First Coast recommends that you register more than one multifactor authentication (MFA) device. To register a second or third device, follow the steps you took in registering your initial MFA device. When logging into SPOT, you will select only one of these devices to receive your MFA passcode.
The microSD removable miniaturized Secure Digital flash memory cards were originally named T-Flash or TF, abbreviations of TransFlash. TransFlash and microSD cards are functionally identical allowing either to operate in devices made for the other.
Unlike the larger SD memory cards, TF memory cards are much smaller. Most cell phones use this type of memory card to store video and audio files. You can also move most of your apps to one when your phone's storage becomes too full.
