Components

K9-Mail is a free and open source 100% email client application for android. It looks very clean and simple, so it is very easy to use, this application also has a very small size, and runs smoothly when used. Users can find some important features in it. And after trying to use this app, I did not find the Add Passcode Lock feature in this app. Though this feature is very helpful user and very useful to use.

Proposal

Add the "Password Passcode" feature in the K9-MAIL app, the developer should add a feature in the Settings section of the app, which is in Account Settings and place it in a public section, so users can use this feature easily. The developer must modify the common parts to add the feature, and grant the user access to enable the passkey and the permission to change the passcode.

Mockups / Examples

An example image after the developer adds the "Passcode Lock" feature in the Settings section.

Benefits

Users of the K9-MAIL app will benefit greatly after the developer adds the "Passcode Lock" feature in the Settings section of the app, the user feels very lucky because of the "Passcode Lock" feature in the Settings section, as the user can set the feature to be enabled, K9-MAIL gets protection and asks users to enter a passcode when opening the app, so users do not have to worry about unwanted stuff like inbox theft and more, because K9-MAIL app has been protected by password lock feature, and not all people can open the app and run the K9-MAIL app.
