Leather Case for Token2 Dual Interface FIDO2 Security Keys
Protect your key while keeping it fully usable.
We do not recommend attaching the Token2 key directly to a keyring, as the body is made of plastic and may wear or break over time. This custom-fit leather case adds a layer of protection and durability, making it easier and safer to carry your key every day.
- Designed for Token2 Dual Interface FIDO2 keys (USB-A & USB-C)
- Expose either USB-A or USB-C depending on your preference
- Touch sensor accessible – use the key without removing it
- Snap button and keyring loop for convenient everyday use
- Made from stitched black leather with a simple, functional design
Does not support dual-interface biometric keys.
