Devise: Create user using only the Email address

How can I create a Signup using Devise where instead of the user entering both his email and password during sign up, all he needs to enter is an email and then get the Password generated through his email?

I'm trying to make sign up as simple as possible and I figured out that since devise is capable of sending out an activation email already, why not just piggy back on that and send a generated Password and confirm at the time of login?

Thanks for any help :)

You can use the Devise's friendly token in your controller:

password = Devise.friendly_token.first(8)
User.create(email: '[email protected]', password: password, password_confirmation: password)

The friendly_token is a string containing A-Z, a-z, 0-9, “-” and “_”.

Source code here:

def self.friendly_token
  SecureRandom.urlsafe_base64(15).tr('lIO0', 'sxyz')
end

and here for more info:

def self.urlsafe_base64(n=nil, padding=false)
  s = [random_bytes(n)].pack("m*")
  s.delete!("\n")
  s.tr!("+/", "-_")
  s.delete!("=") if !padding
  s
end
