Though these are easier to remember, they're also easier to hack. It's all too easy to rely on weak passwords like your birthday or pet's name, but you shouldn't be careless. With password crackers more advanced than ever, you'll want to use unique passwords for every account that you have.
Password manager service options we haven't reviewed.Other password managers worth considering.What is a password manager, and why do you need one?.It removes the need to manually ssh-add keys with nonstandard names and stores key passwords if set in the macOS keyring. The following stanza can be adapted and placed in ~/.ssh/config. D prevents ssh-agent from forking, and -a ~/.ssh/agent directs the agent to create a socket file at that location that is referenced in $SSH_AUTH_SOCK. It runs the command /usr/local/bin/ssh-agent -D -a ~/.ssh/agent. This plist was created using the launchd plist generator over at zerowidth. usr/local/bin/ssh-agent -D -a ~/.ssh/agentĪnd load it with launchctl load -w ~/Library/LaunchAgents/_ist. If you do, you can load it directly to the ssh-agent using ssh-add -K, or write the key handle and public key to disk using ssh-keygen -K It is your choice whether to use a resident key. For this reason, a good pin is important. Additionally, it may reduce the security of your ssh key as they could use it if they steal the hardware device. However, your key may or may not support it and only a limited number of resident keys may be stored on a device. The private key file is actually a key handle that cannot be used without the hardware token, however, the hardware token can also not be used without the key handle.Ī resident key solves this problem by storing the key handle on the device. When generating the key, ssh-keygen will create private and public key files that look similar to normal ssh key. If not, use options 3 or 4.Ī U2F attestation requires a key handle to be sent to the device. You must choose if you want to store the key handle as a resident key on the device. If it does not work due to device incompatibilities, fall back on ecdsa-sk (Options 2 or 4) You must choose between ed25519-sk and ecdsa-sk. Using it on macOS with full support for ssh-agent is a bit more complex. SSH 8.2 introduced support for using any U2F key in place of a private key file.
