The second is to practice good password habits: use unique, randomly-generated strong passwords for every account. Bitwarden can help with a tool called “Inactive 2FA Report” that will check all logins in the vault against a list of sites that offer TOTP as a two-step login and flag logins that haven’t had it set up. The first is to implement any form of two-step login (2FA, two-factor authentication, multifactor authentication) on every account that offers it. There are two important steps that anyone can do today to improve security on the internet. Two-step login stops these bad actors in their tracks! Data breaches and password leaks may reveal an accidentally reused password, or a brute force attack could try to guess your password millions of times a minute. Hardware keys are widely agreed to be the most secure form of identity verification.Īny type of two-step login provides significantly more security than leaving your account unprotected! Without two-step login your account is protected only by a single password. Text message (SMS) codes are generally known as the least secure as phone numbers can be vulnerable to SIM-swap attacks. Depending on the site, you could be asked for a code sequence that was sent to you via text message or email, or a timed one time password (TOTP) from an authentication app as examples.ĭifferent types of two-step login methods have varying levels of security and resilience to attacks. In contemporary terms, after you’ve enabled two-step login on any of your accounts, logging in with a username and password from an unrecognized device will trigger the second step. Overhearing the magic phrase in a tavern won’t give them access alone! For example, in order for an adventurer to gain entrance to the forbidden mystical city, they must speak the magic phrase (that they know) and present the enchanted medallion (that they have). Two-step login can be thought of in terms of having something you know, and something that you have. It’s so important that even though it’s been covered extensively in a Bitwarden blog, webcast, and field guide it’s worth revisiting again here. Two-step login, also known as two-factor authentication, 2FA, and multifactor authentication, is a way to drastically increase the security on any of your accounts. A hardware key is considered very secure since it can’t be duplicated and requires a physical device to be carried by the user. When plugged into a computer or held close to a phone to be read by NFC (near-field communication) the security key authenticates the user. One FIDO2 example is a hardware security key, which is a special device that may look like a USB thumb drive. Compared to other protocols such as OTP (one-time passcodes) FIDO2 offers greater protection because it is stronger against phishing and fake websites thanks to the use of a public/private key pair as part of its security. ![]() Other technologies under this umbrella term include WebAuthn, an open web standard, and CTAP both run under-the-hood to help keep everything secure. In other words, they are who they say they are. The group, including internet industry leaders, worked together to develop the standard and advance online authentication, specifically for reducing the reliance on passwords.įIDO2 serves as a protocol for applications, servers, and other devices to communicate with each other, ensuring that the user trying to log in is authenticated appropriately. FIDO stands for Fast IDentity Online (not the name of a dog), as shorthand for the authentication standard created by the FIDO Alliance, an open industry association.
