If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.

:gift: OTP Generator & Verifier

GitHub License Latest Version on Packagist GitHub Tests Action Status Total Downloads

This is a tool to create OTP with an expiry for PHP without using any Database. This is primarily a Laravel Package but it can be used outside of Laravel also.

:package: Installation

Via Composer

To publish the config file for laravel you can run

:fire: Usage in Laravel

Import the facade class:

Generate an OTP:

The above generated OTP will only be validated using the same unique secret within the default expiry time.

TIP: OTP is generally used for user verification. So the easiest way of determining the uniqe secret is the user's email or phone number. Or maybe even the User ID. You can even get creative about the unique secret. You can use md5($email) the md5 of user's email or phone number.

Match an OTP:

Other Generate & Match Options:

There are other ways of generating or matching an OTP:

Make sure to set the same config during checking. What that means is, if you have used 8 digits and 30 min during creation you will also have to use 8 digits and 30 min during checking as well.

Here, in the above example for matching the OTP we can see that the same config is required when matching the otp with the secret which was used during creation of the OTP.

Security Advantage: - The main advantage of using the same config while matching is some third person cannot use this tool to generate the same otp for the user in question if he doesn't know the config.

:ocean: Helper usage

You can use the package with provided helper function as well

:heart_eyes: Usage outside Laravel

Install the package with composer the same way as above. Then just use it with the helper function provided. Generate:

All of the functionalities are the same as it is been documented in Laravel Usage section. Here just use the instance instead of the Static Facade.

NOTE: You don't need to do anything if you are using Laravel. It will detect the default cache store of laravel.

Example:

Also, keep in mind that while matching the OTP keep the digit & expiry config same as when the OTP was generated.
