README
PasswordlessAuth
PasswordlessAuth provides functionality that can be used in an authentication or verification system, such as a passwordless or multi-factor authentication flow, or for verifying a user's ownership of a phone number, email address or any other identifying address.
- Generate verification codes
- Verify a user's attempt at entering a code
- Rate limit attempts
- Expire codes
This library doesn't deal with sending the codes to recipients.
See Usage for example usage.
Documentation
Documentation is available at https://hexdocs.pm/passwordless_auth
Installation
Add :passwordless_auth to your list of dependencies in mix.exs:
def deps do
[
{:passwordless_auth, "~> 0.3.0"}
]
end
Configuration
The following PasswordlessAuth config can be set in your config/config.exs file:
config :passwordless_auth,
# How long codes are valid for
verification_code_ttl: 300, # seconds; default: 300
# Rate limiting: how many failed attempts are allowed before the timeout is applied
num_attempts_before_timeout: 5, # default: 5
# Rate limiting: how long to disallow attempts after the limit has been reached
rate_limit_timeout_length: 60, # seconds; default: 60
# How often to clear out expired codes
garbage_collector_frequency: 30 # seconds; default: 30
Usage
Here's an example where the code is sent to a recipient's phone number using ExTwilio.
1. Generate a verification code for the recipient
User enters their phone number to request a verification code.
code = PasswordlessAuth.generate_code("+447123456789")
=> "123456"
2. Send the code to the recipient
This library doesn't deal with SMS or emails, so this bit is up to you.
ExTwilio.Message.create(%{
to: "+447123456789",
body: "Your code is #{code}"
})
3. Verify the code
Recipient receives a text message with their verification code. They enter it into your system and you verify that it is correct.
attempt_code = "123456" # The user's attempt at entering the correct verification code.
PasswordlessAuth.verify_code(
"+447123456789",
attempt_code
)
Returns true or false.
Once a code has been verified, you can remove it so that it can't be used again before it expires.
PasswordlessAuth.remove_code("+447123456789")
