Como receber notificação no smartphone ao iniciar Sistema no PC?

Olá, gostaria de saber se existe alguma forma de receber um alerta(email, mensagem ou notificação) no meu smartphone toda vez que alguém fizer login no meu sistema.
Uso o PopOs-20.04 LTS

Modify or create /etc/ssh/sshrc with the following contents:

ip=`echo $SSH_CONNECTION | cut -d " " -f 1`

logger -t ssh-wrapper $USER login from $ip
echo "User $USER just logged in from $ip" | sendemail -q -u "SSH Login" -f "Originator <[email protected]>" -t "Your Name <[email protected]>" -s &

This will effectively notify you by email anytime someone logs in through SSH, and the login will be logged in the syslog.

Note: You’ll need the sendemailpackage (sudo apt-get install sendemail) for the email notification to work.

Note: works with port forwarding, but with -N option not.
