How can i potty train a 2 year old?

A toddler who walks: from room to room, pulls his/her pants & pull-up or underpants down & says " pee-pee", "poo-poo" or potty to indicate he/she senses the urge to "go" is ready for daytime toilet training. If not, you may create a behavior problem . There's no harm in putting a potty chair in the bathroom for the child to sit on while you model using the toilet, but don't force the child to sit on it.
