How Protectimus Bot work

It’s the most convenient method for receiving one-time passwords. There’s no more need to pay SMS providers, buy hardware OTP tokens, or ask your users to install extra OTP generator apps. Users need only add the ProtectimusBot chatbot to their usual messaging app. And after a quick, 15-second setup process, they will receive one-time passwords and other important messages.

Free

Authentication through chatbots on Telegram, Facebook Messenger, Viber and other messaging apps is completely free. It’s just as easy as SMS, but it lets you avoid unnecessary costs. What’s more, it’s possible to combine one-time password delivery with delivery of important messages, such as information about deposits and withdrawals, allowing you to completely put an end to your SMS expenses.

Secure

Using messaging apps to deliver one-time passwords is secure. Messaging apps use reliable message encryption algorithms, and access to these apps is additionally protected by a password. On top of that, this OTP delivery method allows the use of HOTP and TOTP password generation algorithms, and supports CWYS (Confirm What You see) data-signing function, which protects data even in the event that a OTP password is intercepted by a hacker.

Easy setup

Setting up two-factor authentication using chatbots on Viber, Telegram, Facebook Messenger and other messaging apps requires minimal effort. The user just needs to find the ProtectimusBot chatbot in their usual messaging app and send it the /getid command. He or she will receive a chat ID to send to Protectimus. Having received the chat ID, Protectimus will connect the new user in just a few moments.

At the moment, my assessment of the company’s work is 10 out of 10. An important factor in choosing this two-factor authentication provider was the possibility of customizing the 2FA system for our project. After we got in touch with the Protectimus team and explained the task, they implemented the necessary functionality for us free of charge. There were no problems. Everything works well.

Cristian G, System Administrator at SICIM

Protectimus was chosen because of their unique Dynamic Strong Password Authentication (DSPA) technology. Using this product, we added 2FA to all the systems we needed to protect in one fell swoop, as it allowed us to integrate two-factor authentication services straight with Active Directory. We have been using the Protectimus two-factor authentication platform for a year and are satisfied with this product.

Mauro S., Xchanging Italy a DXC Technology

Over the past years, we’ve had only positive cases of working together. Protectimus helped us at every stage, from integration to adding additional features that solved our specific tasks. Using Protectimus, we are confident that Volet infrastructure and users are well protected. Protectimus gives us what money can’t buy – not a sense of security, but REAL security. I highly recommend it for implementation.

Artem Sh., Info Security Director at Volet
