To add to this: * Add an authentiction subkey and you now have a drop-in-replacement for ssh keys. * Password managers like "Password Store" use a git repository full of gpg encrypted files as a backend allowing for a secure password management solution that only decrypts the credential you need vs decrypting -all- of them at once like most popular tools. * If you make use of the solid smartcard support you can even avoid your keys ever being exposed to system memory where malware can steal them.
