Tips for using USB security keys

Before you start using USB security keys daily, you need to know how to handle them. We have prepared some tips to help you on your security journey and ensure smooth sailing.

1. Always have more than one key

Since USB security keys are small and lightweight, it’s easy to forget you are carrying them around. They can easily fall out of your pocket or get lost somewhere. In such cases, you should always have a backup plan you can rely on. Have at least two of the same keys to access your account, even if you accidentally lose the primary key.

2. Make sure your keys are compatible with the software

Since different types of keys are available, some are only compatible with a few apps/software. For instance, you can find different keys for Windows and Mac devices. Before you purchase the key, you should research and determine whether it is compatible with your accounts, operating system, and other features so you don’t waste time and money.

3. Security key malfunction and data loss

USB devices can be very vulnerable and prone to malfunction. If you are not handling these devices well or accidentally catch a virus, you may lose all the data you have stored on them. In such cases, it’s crucial to have a third-party software solution to recover your data as quickly as possible.

One such program is Wondershare Recoverit – it’s one of the most successful recovery solutions on the market that will retrieve your valuable data. You can get your data back no matter the type of files or devices you use.

You should download the program just in case things go sideways – and if they do, follow the guide below for the best data recovery journey:

  1. Open Recoverit on your PC.
  2. Insert your USB security key.
  3. Select Hard Drives and Locations from the available recovery options.
