v.email('The email address is badly formatted.')
),
password1: v.pipe(
v.string(),
v.nonEmpty('Please enter your password.'),
v.minLength(8, 'Your password must have 8 characters or more.')

password2: v.string(),
}),
v.forward(
v.partialCheck(
'password1'], ['password2',
(input) => input.password1 === input.password2,
'The two passwords do not match.'
),
'password2'
