NAME

URI::otpauth - URI scheme for secret keys for OTP secrets. Usually found in QR codes

VERSION

Version 5.29

SYNOPSIS

  use URI;

  # optauth URI from textual uri
  my $uri = URI->new( 'otpauth://totp/Example:alice@google.com?secret=NFZS25DINFZV643VOAZXELLTGNRXEM3UH4&issuer=Example' );

  # same URI but created from arguments
  my $uri = URI::otpauth->new( type => 'totp', issuer => 'Example', account_name => 'alice@google.com', secret => 'is-this_sup3r-s3cr3t?' );

DESCRIPTION

This URI scheme is defined in https://github.com/google/google-authenticator/wiki/Key-Uri-Format/:

SUBROUTINES/METHODS

new

Create a new URI::otpauth. The available arguments are listed below;

  • account_name - this can be the account name (probably an email address) used when authenticating with this secret. It is an optional field.

  • algorithm - this is the cryptographic hash function that should be used. Current values are SHA1, SHA256 or SHA512. It is an optional field and will default to SHA1.

  • counter - this is only required when the type is HOTP.

  • digits - this determines the length of the code presented to the user. It is an optional field and will default to 6 digits.

  • issuer - this can be the application / system that this secret can be used to authenticate to. It is an optional field.

  • label - this is the issuer and the account name joined with a ":" character. It is an optional field.

  • period - this is the period that the TOTP code is valid for. It is an optional field and will default to 30 seconds.

  • secret - this is the key that the TOTP/HOTP algorithm uses to derive the value. It is an arbitrary byte string and must remain private. This field is mandatory.

  • type - this can be 'hotp' or 'totp'. This field will default to 'totp'.
