# [[Setting a PIN on YubiKey]]
![[Setting a PIN on YubiKey.svg]]
To set a PIN on a YubiKey that must first be entered before it can be used for SSH keys or [[MFA]], you need to install the [[YubiKey Manager CLI]]:
```
brew install ykman
```
Then, run the command:
```
ykman fido access set-pin
```
You'll be prompted to enter a four-digit PIN. Follow the prompts.
Once you do so, you'll need to enter your PIN when you use the YubiKey (usually upon opening a terminal).
