Recovery Codes

Generate recovery/backup codes to provide a way for your users to recover from a lost two factor auth, or any problem with it.

Install

Via Composer

$ composer require pragmarx/recovery

Usage

Basic array usage

$this->recovery = new PragmaRX\Recovery();

$this->recovery->toArray();

Collection

If you are using Laravel or install a package like Collect, you can:

$this->recovery->toCollection();

You can also define a different collection function to be used:

$this->recovery->collectionFunction('alternateCollection');

$this->recovery->setCount(8)->toCollection();

Json result

$this->recovery->toJson();

Should give you

[  
   "C0r2Xp4o1v-oG3pteKXw3",
   "oLuSmVeJ7D-t4wnJVwkuC",
   "XdPXXJy3J6-Gl3d0EwWt7",
   "Bn8twjUJRt-Lv3KaAFwjR",
   "SrnMagyGRg-eC7WPyFQ17",
   "mRO4WPJpRN-hgfrUZqqZd",
   "xBZtyFOrJZ-Tbpg0pSvzf",
   "eiPFmwvJp0-oSqdNKclDH"
]

Changing the result values/sizes

$this->recovery
     ->setCount(8)     // Generate 8 codes
     ->setBlocks(5)    // Every code must have 7 blocks
     ->setChars(16)    // Each block must have 16 chars
     ->toArray();

Should give you

]

Numeric or alpha?

$this->recovery
     ->numeric()       // Generate numeric only codes
     ->toArray();
     
$this->recovery
     ->alpha()        // Get back to default alpha generation
     ->toArray();

Upper, lower and mixed case

$this->recovery
     ->lowercase()    // All lower
     ->toArray();
     
$this->recovery
     ->uppercase()    // All upper
     ->toArray();
     
$this->recovery
     ->mixedcase()    // Get back to default mixed case
     ->toArray();
