yubikey-agent -setup fails with error about default

[AriESQ]

I cannot do yubikey-agent -config even after trying to reset the yubikey. Sometimes the error is the default PIN did not work and sometimes the error is the default management key did not work.

Fresh out of package yubikey nano 5c. (Firmware 5.4.3)
macOS: 12.3.1 on M1 Apple Silicon
yubikey-agent 1.5 from homebrew

Your YubiKey now has the default PIN, PUK and Management Key:

� The PIN is up to 8 numbers, letters, or symbols. Not just numbers!
❌ The key will be lost if the PIN and PUK are locked after 3 incorrect tries.

Choose a new PIN/PUK:
Repeat PIN/PUK:

‼️  The default PIN did not work

If you know what you're doing, reset PIN, PUK, and
Management Key to the defaults before retrying.

If you want to wipe all PIV keys and start fresh,
use --really-delete-all-piv-keys ⚠️

While the lack of response is concerning, I have just solved the same problem with this #78 (comment)

TL;DR: the PIN must be at least 6 chars; maybe you have to use yubikey-agent --really-delete-all-piv-keys -setup
