Generating public/private ecdsa-sk key pair.
You may need to touch your authenticator to authorize key generation.
Enter PIN for authenticator:
Enter file in which to save the key (/home/tester/.ssh/id_ecdsa_sk):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/tester/.ssh/id_ecdsa_sk
Your public key has been saved in /home/tester/.ssh/id_ecdsa_sk.pub
The key fingerprint is:
SHA256:veX8eVHMp6r5jmrCtyonIK/bymj/22cyB8KytayhCz0 tester@192.168.88.141
The key's randomart image is:
