If the QR-codes don't match, you will see a red cross mark and a message that says "Encryption keys don't match". This means that there may be a potential security breach. You should stop the communication and contact your interlocutor by another means.

How to compare SafeUM with other popular messengers
SafeUM is not the only secure messenger available on the market. There are other popular messengers that claim to offer security and privacy for their users. However, not all of them are equally reliable and trustworthy. In this section, we will compare SafeUM with three other popular messengers: Telegram, WhatsApp, and Signal. We will use the following criteria to compare them: encryption, registration, features, functionality, user-friendliness, and accessibility.
SafeUM vs Telegram: which one is more secure and private?
Telegram is a popular messenger that has over 500 million active users worldwide. It is known for its fast speed, cloud-based storage, and large group chats. However, when it comes to security and privacy, Telegram has some drawbacks that make it less secure and private than SafeUM. Here are some of them:
Telegram does not use end-to-end encryption by default. It only uses end-to-end encryption for secret chats, which are limited to two participants and do not support group chats, voice calls, or file sharing. For regular chats and calls, Telegram uses server-client encryption, which means that the data is encrypted between your device and Telegram's servers, but not between Telegram's servers and your interlocutor's device. This means that Telegram can access your data if they want to or if they are forced to by law enforcement or hackers.
Telegram requires a phone number for registration. This means that you have to provide your personal information to use Telegram, which can compromise your anonymity and privacy. Moreover, Telegram does not allow you to use multiple accounts on one device or to change your phone number without losing your data.
Telegram does not have a secure QR-code verification system. It only has a picture-based verification system that shows you an image of an animal that represents your interlocutor's encryption key. However, this system is not very reliable or user-friendly, as it does not show you the actual key or allow you to scan it with your camera.
In contrast, SafeUM uses end-to-end encryption for all chats, calls, and files, regardless of the number of participants or the type of data. It also does not require a phone number for registration, and allows you to use multiple accounts on one device and to change your phone number without losing your data. Moreover, it has a secure QR-code verification system that shows you the actual encryption keys of your interlocutors and lets you scan them with your camera. Therefore, SafeUM is more secure and private than Telegram.
SafeUM vs WhatsApp: which one has more features and functionality?
WhatsApp is another popular messenger that has over 2 billion active users worldwide. It is known for its simplicity, reliability, and wide reach. It also uses end-to-end encryption for all chats, calls, and files, which makes it secure and private. However, when it comes to features and functionality, WhatsApp has some limitations that make it less feature-rich and functional than SafeUM. Here are some of them:
WhatsApp does not have encrypted group chats. It only has encrypted group calls, which are limited to eight participants. For group chats, WhatsApp uses a different encryption protocol that does not guarantee the security of the data. This means that WhatsApp can access your group chat data if they want to or if they are forced to by law enforcement or hackers.
WhatsApp does not have encrypted files. It only has encrypted photos, videos, documents, and voice messages. For other types of files, such as audio files, zip files, or apk files, WhatsApp does not encrypt them. This means that WhatsApp can access your file data if they want to or if they are forced to by law enforcement or hackers.
WhatsApp does not have account access control or security alerts. It only has a two-step verification system that requires you to enter a PIN-code when you register your phone number on a new device. However, this system does not protect you from unauthorized access or suspicious activity on your account. You cannot choose different levels of account access with different PIN-codes, or enable security alerts for any unusual activity on your account.
In contrast, SafeUM has encrypted group chats that support up to 1000 participants and use group keys for encryption. It also has encrypted files of any type and size that use file keys for encryption. Moreover, it has account access control and security alerts that let you choose different levels of account access with different PIN-codes, and enable security alerts for any unusual activity on your account. Therefore, SafeUM has more features and functionality than WhatsApp.
SafeUM vs Signal: which one is more user-friendly and accessible?
Signal is another secure messenger that has over 50 million active users worldwide. It is known for its open-source code, nonprofit status, and endorsement by privacy advocates. It also uses end-to-end encryption for all chats, calls, and files, which makes it secure and private. However, when it comes to user-friendliness and accessibility, Signal has some drawbacks that make it less user-friendly and accessible than SafeUM. Here are some of them:
Signal requires a phone number for registration. This means that you have to provide your personal information to use Signal, which can compromise your anonymity and privacy. Moreover, Signal does not allow you to use multiple accounts on one device or to change your phone number without losing your data.
Signal does not have cross-platform compatibility. It only supports Android, iOS, Windows, macOS, and Linux platforms. It does not support Windows Phone or Web platforms. This means that you cannot use Signal on some devices or browsers.
Signal does not have customizable interface. It only has a default theme, font, wallpaper, sound, and notification settings. You cannot change the appearance of Signal according to your preferences.
In contrast, SafeUM does not require a phone number for registration, and allows you to use multiple accounts on one device and to change your phone number without losing your data. It also supports all platforms, including Android, iOS, Windows Phone, Windows, macOS, Linux, and Web. Moreover, it has a customizable interface that lets you change the theme, font, wallpaper, sound, and notification settings. Therefore, SafeUM is more user-friendly and accessible than Signal.
