I was trying to set up 2fa in my kirby instance and getting issue with email setup. I have added the required details including smtp server, username, password, port in config.php but i am still not able to get any code in my email.
Is there something i am missing to setup, the documentation is not that clear on this!
Please help
There are two steps:
You need to enable 2FA in the config: auth | Kirby CMS
You need to set-up email transport
If you have done this, I’d check if sending emails works with your settings, by trying to send an email via the $kirby->email() from a template:
I have done the mentioned steps, although i am not getting how i can check if i can send emails or not?
Here we have the first problem, you may only have one return statement in your config! return returns the script execution to the calling script, hence anything after will not be executed.
Ok, well, please try to set debugging for authentication like explained here: auth | Kirby CMS
Then check if you get any errors in your php error logs that help to find out what’s going on.
Also, try to send an email according to the email documentation from a template like I suggested above.
On a side note, please copy/paste your code here instead of adding screenshots. Thank you!
Well i tried to debug the issue, seems like there is some hardcoded invalid email - noreply@<server_ip>

The below-mentioned snippet is creating an issue,
$kirby = $user->kirby();
$kirby->email([
'from' => $kirby->option('auth.challenge.email.from', 'noreply@' . $kirby->url('index', true)->host()),
'fromName' => $kirby->option('auth.challenge.email.fromName', $kirby->site()->title()),
'to' => $user,
'subject' => $kirby->option(
'auth.challenge.email.subject',
I18n::translate('login.email.' . $mode . '.subject', null, $user->language())
),
'template' => 'auth/' . $mode,
'data' => [
'user' => $user,
'site' => $kirby->system()->title(),
'code' => $formatted,
'timeout' => round($options['timeout'] / 60)
]
]);
In my case, I am using docker in my private server and accessing the app with IP at port 5555.
Fixed!!
The change i did was from
'from' => $kirby->option('auth.challenge.email.from', 'noreply@' . $kirby->url('index', true)->host()),
to
'from' => $kirby->option('auth.challenge.email.from', 'noreply@yourdomain.com'),
Thanks 
I hope you didn’t change this in the source code?
