If your Mac has a Touch Bar, use Touch ID preferences to enable your Mac to be unlocked with your fingerprint, add one or more fingerprints to your user account, and enable Touch ID to be used to make purchases with Apple Pay and from the iTunes Store, App Store, or iBooks Store. I found that if I go to Settings>General>Passcode&Fingerprint>Fingerprints turn off iTunes & App Store then turn it back on. It should prompt you to enter your Apple ID password. When I went back to the app store it prompted me for my fingerprint. Using fingerprint reader for encryption or ssh login? And I store my passwords, such as those for web logins, in an encrypted file, using a password only for this occasion to decrypt the password. > > > 3) Related to 1, use fingerprint reader to decrypt the ssh key > > when adding it to ssh-agent. > > Exactly same as in 1). Touch ID is the name of Apple's fingerprint identity sensor. It's a form of biometric security that's meant to be more convenient than entering a passcode or password, especially on iPhones and iPads we use hundreds of times a day. ![]() ![]() How To Get A New App Store Password For PhoneRun the following command to retrieve your SSH key fingerprint ( -l means 'list' instead of create a new key, -f means 'filename'): $ ssh-keygen -lf /path/to/ssh/key So for example, on my machine the command I ran was (using RSA public key): $ ssh-keygen -lf ~/. Card reader for mac not working. ssh/id_rsa.pub 2048 00:11:22:33:44:55:66:77:88:99:aa:bb:cc:dd:ee:ff /Users/username/.ssh/id_rsa.pub (RSA) With newer versions of ssh-keygen, run ssh-keygen -E md5 -lf if you want the same format as the old (thanks, Lloyd Dewolf). Bonus information: ssh-keygen -lf also works on known_hosts and authorized_keys files. Find most public on a Linux/Unix/OS X system with find /etc/ssh /home/*/.ssh /Users/*/.ssh -name '*.pub' -o -name 'authorized_keys' -o -name 'known_hosts' (If you want to see inside other users' homedirs, you'll have to be root or sudo.) The ssh-add -l is very similar, but lists the fingerprints of keys added to your agent. (OS X users take note that magic passwordless SSH via Keychain is not the same as using ssh-agent.). The newer SSH commands will list fingerprints as a SHA256 Key. For example: ssh-keygen -lf ~/.ssh/id_dsa.pub 1024 SHA256:19n6fkdz0qqmowiBy6XEaA87EuG/jgWUr44ZSBhJl6Y (DSA) If you need to compare it against an old fingerprint you also need to specify to use the MD5 fingerprint hashing function. But not as much accurate as Nuance’s Dragon. If you know we have also built in free tools for all Mac users known as “ Dictation & Speech“. Mac Fingerprint Reader Store Password For SshSsh-keygen -E md5 -lf ~/.ssh/id_dsa.pub 2048 MD5:4d:5b:97:19:8c:fe:06:f0:29:e7:f5:96:77:cb:3c:71 (DSA) Also available: -E sha1 Update. DSA keys for SSH should no longer be used, the older RSA key or newer ecliptic keys should be used instead. To those 'admins' that keep editing the command I used in the above. STOP CHANGING IT! A key pair (the private and public keys) will have the same fingerprint; so in the case you can't remember which private key belong to which public key, find the match by comparing their fingerprints. The most voted answer by Marvin Vinto provides the fingerprint of a public SSH key file. The fingerprint of the corresponding private SSH key can also be queried, but it requires a longer series of step, as shown below.
