Storing Credentials

This article applies to:


The YubiKey 4, YubiKey 4 Nano, YubiKey 4C, and YubiKey 4C Nano, each have two “configuration slots”. Users can program each slot with a single credential, such as OTP and Challenge-Response (such as for Microsoft Windows or Mac OS X account login) or static password.

In addition, you can also:

  • Configure the YubiKey as a smart card (PIV) and program the YubiKey for touch-to-sign.
  • Store one OpenPGP private key and three subkeys (or just three subkeys, recommended).
  • Store up to 32 OATH credentials (TOTP or HOTP) on the YubiKey and access them using the Yubico Authenticator companion application.
  • Store  an unlimited number of U2F credentials.

On the YubiKey NEO and YubiKey NEO-n, there are two “configuration slots” on each key. You can program each slot with a single credential, such as OTP and Challenge-Response (such as for Microsoft Windows or Mac OS X account login) or static password.

In addition, you can also:

  • Configure the YubiKey as a smart card (PIV).
  • Store one OpenPGP private key and three subkeys (or just three subkeys, recommended).
  • Store up to 28 OATH credentials (TOTP or HOTP) on the YubiKey and access them using the Yubico Authenticator companion application.
  • Have an unlimited number of U2F credentials on these YubiKeys.

Legacy products: On the YubiKey Edge/Edge-n or YubiKey Standard/Nano, there are two “configuration slots” on each key. You can program each slot with a single credential, such as one for OTP and one for Challenge-Response (such as for Microsoft Windows or Mac OS X account login) or static password. On a YubiKey Edge/Edge-n or YubiKey Standard/Nano, use the Yubico Authenticator companion application to create and access two (2) OATH-TOTP credentials (one in each configuration slot), as long as no other credentials are stored in those slots.
