One-time tokens can significantly enhance security in your Spring applications. Here’s a quick guide on implementing a one-time token login system:
1. Generate a Token: When a user triggers the login process, generate a unique token. You can utilize java.util.UUID for this purpose:
String token = UUID.randomUUID().toString();
2. Send Token via Email: Email the token to the user’s registered email address. This ensures only they can log in.
3. Validate Token: When the user clicks the login link, validate the token. If valid, allow access; if not, deny entry.
4. Token Expiry: Ensure that the token expires after a certain time, usually within a few minutes, to enhance security. You could use a database or in-memory store to manage token states.
5. Cleanup: After successful login or expired tokens, remove them from your store to prevent misuse.
Implementing this approach protects user sessions from unauthorized access while ensuring a smooth login experience! 😊🔐

Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
Telegram and Signal Havens for Right-Wing Extremists
Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
