yes, there are ... for ssh and gpg see:

$ ps ax|grep bin/[a-z]*-agent
  52085 ?        SLs    0:02 /usr/bin/gpg-agent --supervised
  75230 ?        S      0:00 /usr/bin/ssh-agent -D -a
/run/user/1000/keyring/.ssh
$

sudo works a tad different handling the timeut for its passphrase cache
internally ... take a look at the sudo manpage, specifically at the -k
option for this ...
