JPwd

This extension allows you to show a password in any site in clear text.
It offers the option to do this either by double clicking on the password field, or by hovering your mouse on it.
This helps in making sure that you typed the password correctly, or remembering the saved password (if you allowed Chrome to save passwords).

You can hide the password by double clicking again on the password field, or moving your mouse out of the password field.
This extension does not record, upload, save or remember your passwords, it simply changes the password field to plain text field for your convenience.
