Logging into device with other set of credentials

If I run the below code... it will login into the router and then changes to privilege mode and then stores the running configuration information to an array.
In this program, I have included the username and password .
In case the username and password is wrong.. it will re login for 2 times and then terminate the program.

Now instead of that.. I want to verify the username and password..

=> if the credentials are correct... then it should continue..
=> if the credentials are wrong(should not check for 2nd time... then it should check with other set of credentials(mentioned in the program..

I am confused to convert the below program as per my above requirement.

Code:

 use strict;
 use warnings;
 
 use Net::Appliance::Session;
 
 my $ios_device_ip = '10.250.249.215';
 
 my $ios_username        = 'cisco';
 my $ios_password        = 'cisco';
 my $ios_enable_password = 'cisco';

#my $user2 = 'newcisco';
#my $pass2 = 'newpass';
#my $enablepassnew = 'cisco'; 

 my $running_config_file = "$ENV{HOME}/running_config.txt";
 
 my $session_obj = Net::Appliance::Session->new(
Host => $ios_device_ip,Transport => 'SSH',  );
 
 # give verbose output whilst we run this script
 $session_obj->input_log(*STDOUT);
 
 # try to login to the ios device, ignoring host check
 $session_obj->connect(
     Name => $ios_username,
     Password => $ios_password,
     SHKC => 0
 );
 
 # drop in to enable mode
 $session_obj->begin_privileged($ios_enable_password);
 
 # get our running config
 my @running_config =  $session_obj->cmd('show running');
 
 # chop out the extra info top and bottom of the config
 @running_config = @running_config[ 2 .. (@running_config -1)];
 
 open(FH, "> $running_config_file")
   or die("Cannot open config file : $!");
 print FH @running_config;
 close FH;
 
 # close down our session
 $session_obj->close;

cifscreds

CIFSCREDS(1)															      CIFSCREDS(1)

NAME

       cifscreds - manage NTLM credentials in kernel keyring

SYNOPSIS

       cifscreds add|clear|clearall|update [-u username] [-d] host|domain

DESCRIPTION

       The cifscreds program is a tool for managing credentials (username and password) for the purpose of establishing sessions in multiuser
       mounts.

       When a cifs filesystem is mounted with the "multiuser" option, and does not use krb5 authentication, it needs to be able to get the
       credentials for each user from somewhere. The cifscreds program is the tool used to provide these credentials to the kernel.

       The first non-option argument to cifscreds is a command (see the COMMANDS section below). The second non-option argument is a hostname or
       address, or an NT domain name.

COMMANDS

       add Add credentials to the kernel to be used for connecting to the given server, or servers in the given domain.

       clear
	   Clear credentials for a particular host or domain from the kernel.

       clearall
	   Clear all cifs credentials from the kernel.

       update
	   Update stored credentials in the kernel with a new username and password.

OPTIONS

       -d, --domain
	   The provided host/domain argument is a NT domainname.

	   Ordinarily the second argument provided to cifscreds is treated as a hostname or IP address. This option causes the cifscreds program
	   to treat that argument as an NT domainname instead.

	   If there are not host specific credentials for the mounted server, then the kernel will next look for a set of domain credentials
	   equivalent to the domain= option provided at mount time.

       -u, --username
	   Ordinarily, the username is derived from the unix username of the user adding the credentials. This option allows the user to
	   substitute a different username.

NOTES

       The cifscreds utility requires a kernel built with support for the login key type. That key type was added in v3.3 in mainline Linux
       kernels.

       Since cifscreds adds keys to the session keyring, it is highly recommended that one use pam_keyinit to ensure that a session keyring is
       established at login time.

       pam_keyinit(8)
