Resetting YubiKey PIV applet...
🔐 The PIN is up to 8 numbers, letters, or symbols.
👆 You'll need it once per session.
❌ The YubiKey gets locked if the wrong PIN is entered 3 times.

Choose a new PIN:
Repeat PIN:
🧪 Reticulating splines...

✅ Done! This YubiKey is secured and ready to go.🤏 When the YubiKey blinks, touch it to authorize the login.🔑 Here's your new shiny SSH public key:ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBNAn1mgsUfJ0eA+cbvPcJBilynMKI9lIlpeZWMAHlZGe3dK62CxD5z7RQ/KdnXxQqQOP/qt1xdDOJDn3NjQrtRU=

Next steps: ensure yubikey-agent is running via launchd/systemd/...,set the SSH_AUTH_SOCK environment variable, and test with "ssh-add -L"

💭 Remember: everything breaks, have a backup plan for when this YubiKey does.
