Password

What is the Password?

I wear shoes but have no feet;
My jumps and speed cannot be beat.
I may live in stables, barns, or pastures;
But you'll also find me living in forests, mountains, or deserts.
I found a home on this website;
Especially at the bottom, jumping and being so bright.
Reyn has collected me from Hasbro, Cygames, porcelain, and stuffies.
You'll also see me in pictures, pins, keycahins, and earrings.
I am loved by Reyn their whole entire life,
Inherited from their grandfather without any strife.

What am I?
The password is in lowercase.
