Our regular readers know that we strongly recommend applying two-step verification wherever it’s possible. In the contemporary world, where database leaks are a standing affair, two-step authentication is not an option, it is, in fact, a must. If you use two-factor verification, an intruder would need to get both the unique password you came up with, and the gadget, which produces the verification codes, to break into your account....
How to Add Two-Factor Authentication to Outlook Web App (OWA)

Protectimus offers both — the Protectimus OWA component for the first approach, and Protectimus DSPA...

HOTP Algorithm Explained
HOTP algorithm, or HMAC based one-time password algorithm, was first published by OATH as RFC 4226 back in 2005. What is OATH? OATH or Initiative for Open AuTHentication is an organization which specified, put together and published the OATH OTP algorithms that lie at the heart of MFA (multi-factor authentication). It is time we look closely at these algorithms, specifically — OATH-HOTP. HOTP algorithm is what allows creating one-time...
