1 Obtaining the Latch plugin

1.1 Prerequisites

SquirrelMail version 1.4.22 or later. (Tested up to 1.4.22).

Curl extensions active in PHP (uncomment "extension=php_curl.dll" or "extension=curl.so"

in Windows or Linux php.ini respectively.

1.2 Obtaining application ID

To obtain the "Application ID" and the "Secret", which are essential to integrate Latch into a service,

it’s necessary to register a developer account in Latch's website: https://latch.elevenpaths.com. On

the upper right side, click on “Developer area”.

Figure 01: “Developer area” in Latch webpage.

In the next screen, tap the button “Register as a developer” and select “Create a new developer account”, a form will appear where you can fill up the required data. Mandatory fields are name, e-mail and password.

Figure 02: Sign in form for developers.

https://latch.elevenpaths.com/




Once completed, an email will be sent, with an activation code to activate the brand new account.

Figure 03: Form to fill up with activation code.

When the account is activated, the user will be able to create applications with Latch and access to developer documentation, including existing SDKs and plugins.

To do so the developer must log on to the Latch website and then access the "Developer area" section (https://latch.elevenpaths.com/www/developerArea), where you can view your applications through the "My applications" section on the side menu.

Figure 04: “My applications” section with user's configured applications.

From the "Add a new application" button, the developer will create a new application, with the specified name, which you want to appear in the end users' mobile application.

https://latch.elevenpaths.com/www/developerArea




Figure 05: Creating an application. The name will be shown on the mobile app.

Information about the application is displayed when it is created and part of this data is editable. The basic data that the developer should use when installing the plugin are the "Application ID" and "Secret". In addition the following additional parameters are in place, which the developer may change at any time, that set the characteristics of your application:

Name: This corresponds to the name of the application that end users see on their devices when they pair the service. They can customize it themselves on their own device if they so wish.

Image: This corresponds to the application icon that will appear in the end-user's device; its size should not exceed 1MB. It is recommended to be in 24-bit png format without alpha channel, and its proportions are 1: 1.

2nd OTP factor (One-time password): This is only available to developers with a subscription model other than "Community". It enables the service to also be protected by a password, which is sent to the end user at the time he/she wants to access the service. The OTP setup can be:

1. Disabled: The option will not appear on the end user's mobile device.

2. Opt in: The end user may choose to use this option to protect the service.

3. Mandatory: The end user will receive a password every time he/she wants to access the service.

Lock latches after request: This is only available to developers with a subscription model other than "Community". This enables the service to be locked automatically once it has been accessed. The “Lock latches after request” setup can be:

1. Disabled: The option will not appear on the end user's mobile device.

2. Opt in: The end user may choose to use this option to protect the service.

3. Mandatory: The service will be locked automatically once it has been accessed. In the latter case, the "Scheduled lock" option would disappear from the service details view.

Contact email and Contact phone: These details will be displayed in the notifications that users will receive when there is a fraudulent attempt to access the service or any of its operations.

Operations: This corresponds to each of the actions included in the service but independent of each other, and that the developer wants to protect with Latch. The number of operations that can be included depending on the model of subscription chosen. In each of the operations, a "2nd OTP factor" (OTP) and a "Lock latches after request" (LOR) can be used. It is not compulsory to create operations and this will depend on the nature of the service to be protected.

https://latch.elevenpaths.com/www/subscription.html







This plugin does not support the use of operations. Tailored implementation through the SDK of the corresponding language must be carried out to add them

Once the setup is complete and the changes have been saved, the new application will appear on the list of the developer's applications. This can be edited whenever you want.

Figure 06: Created application. It may be edited again at any moment.

1.3 Downloading the plugin

From the side menu in developers area, the developer can access the “Documentation & SDKs” section. Inside it, there is a “Plugins and SDKs” menu. Links to different SDKs in different programming languages and plugins developed so far, are shown.

Figure 07: Examples of SDKs and plugins available.

The developer must tap the “DOWNLOAD” button for this plugin to access its source code from the

“Standard plugins” section. A manual on the installation and use of the plugin can also be

downloaded.




2 Installing the plugin

Once the administrator has downloaded the plugin, it has to be added as a plugin in SquirrelMail. Unzip the “latch” folder from the plugin and place the whole content inside “plugins” folder, inside SquirrelMail directory structure, just as shown in the figure.

Figure 08: Unzipping “latch” folder inside SquirrelMail folder structure.

After adding the plugin in SquirrelMail, it has to be activated. Open "config.php” file with any text editor and add ‘latch’ to the existing plugins array. If no plugin is active, the array will not be defined, so a new entry has to be created this way:

$plugins[] = 'latch';

Figure 09: Activating Latch plugin in “config.php” file.




2.1 Configuring the plugin

Once activated the plugin for SquirrelMail, the user has to set the “Application ID” and “Secret” generated in previous steps (see figure 05).

This information has to be manually inserted into “latchConfiguration.php” file, within “latch” folder inside the downloaded plugin. Open this file with any text editor and set “Application ID” and “Secret” respectively in the variables:

public static $applicationId = "";

public static $applicationSecret = "";

Administrator has to save the file.

Figure 10: Setting “Application ID” and “Secret” in “config.inc.php” file.

Now the plugin is installed, the user has to access his SquirrelMail account administration window. In “Options” there will be a new section called “Latch settings”. In there, the user may add the token generated by the app in the mobile and pair the account pressing on “Pair account”.

Figure 11: Accessing SquirrelMail options, where Latch configuration is.




Figure 12: The token, generated by Latch has to be introduced to pair the account.

2.2 Uninstalling the plugin

Uninstalling is simple. Administrator just have to undo the steps done during the installation.

The easier way is to comment out the line code referring the plugin array in config.php. Add: // just as the figure shows.

Figure 13: Comment out the line referring Latch and the plugin will not be operative.

Figure 14: When back to “Options”, Latch options will not be available anymore.

Uninstalling the plugin does not mean that users will no longer have the pairing service of the Latch app (see figures in step 4). This will only happen when users carry out the unpairing or

when the administrator removes the service from the Latch web (see Figure 06).




3 Use of the Latch plugin by end users

Latch does not affect in any case or in any way the usual operations with a service. It just allows or denies actions over it, acting as an independent extra layer of security that, once removed or without effect, will have no effect over the service, which will remain with their original state.

3.1 Pairing a user

When the plugin is configured, users may use it. They need the Latch application installed on their mobile devices, and follow these steps:

Step 1: Within your account of the service that you want to pair, you must go to the site created

by the administrator for pairing with Latch. The way to access this site and its name are

completely dependent on the administrator.

Figure 15: The user should introduce the pairing code generated by Latch here.

Step 2: From the Latch app on the mobile device, the user has to generate the pairing code,

pressing on “Add a new service" at the bottom of the application, and pressing "Generate new

code" will take the user to a new screen where the pairing code will be displayed.

Step 3: Next the same characters displayed on the mobile device must be entered (before they

expire) on the site created by the administrator for pairing with Latch and then tap the button to

confirm the pairing. A notification will be received on the mobile device, announcing that the

service is already paired.




Figure 16: Button that accesses the pairing code.

Figure 17: Generated pairing code. Figure 18: Notification after successful pairing.

Step 4: After pairing, the user will be able to access the accounts list paired with Latch. Users can

check that the pairing was recently added. From this point users can lock and unlock access to

these services simply by tapping the button beside each service name.

Figure 19: Unlocked service. Figure 20: Locked service.

To test Latch, the user needs to lock the service from Latch app, and try to access again introducing the right credentials.

If the configuration is correct, the user will not be able to access in even if the correct credentials were introduced. Additionally, a notification on the mobile device will be received, warning about somebody trying to access the service. The notification includes the email and the phone that the developer stated at when created (Figure 5).




Figure 21: A user accessing. Figure 22: Notification of an unauthorized access attempt.

After unlocking the service from Latch app and introducing the right credentials again, the user will be able to access.

3.2 Unpairing a user

Simply access the section where the pairing initially took place and unpair throught the corresponding element. Finally, an alert indicating that the service has been unpaired will be displayed
