Multi-factor authentication (MFA) is an authentication method in which a computer user is granted access only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something the user and only the user knows), possession (something the user and only the user has), and inherence (something the user and only the user is).Two-factor authentication (also known as 2FA) is a type, or subset, of multi-factor authentication. It is a method of confirming users' claimed identities by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are.
A good example of two-factor authentication is the withdrawing of money from an ATM; only the correct combination of a bank card (something the user possesses) and a PIN (something the user knows) allows the transaction to be carried out.
Two other examples are to supplement a user-controlled password with a one-time password (OTP) or code generated or received by an authenticator (e.g. a security token or smartphone) that only the user possesses.Two-step verification or two-step authentication is a method of confirming a user's claimed identity by utilizing something they know (password) and a second factor other than something they have or something they are. An example of a second step is the user repeating back something that was sent to them through an out-of-band mechanism. Or, the second step might be a six digit number generated by an app that is common to the user and the authentication system.
I've had 2FA go south on one of my NAS (Ds218+).
It's persistently not accepting my authntication code from the Google Authenticator app. Tried it dozens of times - not a fat-finger issue.
DId the SSH trick (below) w/my admin account (not default admin, that's disabled) - but when I try to log...
I recently upgraded my Synology NAS and 2 factor authentication for my Synology account was still working. I've since set a firewall rule to temporarily deny internet traffic to and from the NAS (local LAN traffic still works). Now, 2FA has stopped working and I can't access my Synology account...
I am trying to determine if a Yubikey could be used as an alternative the app for 2FA.
Based on the Synology website:
Which USB security keys does Secure SignIn Service support?
I do see that 2 Yubico models are supported but I am unable to find exactly which 2 models they refer to...
We are using Quickconnect for remote access over the web to our file server. We have 2FA enabled on the NAS, but the web access allows read-only access without requiring the 2FA code. Then there is a link on the upper right where you can login again to get read-write access that asks for the 2FA...
I had disabled my admin account but that broke cloudsync, so I restored it and put in a wild/crazy/long PW to make it secure.
I have a second admin-level account that I can log into, but from that account I don't see a way to re-enable 2FA on the original admin account. I can't log in using the...
I hope all is well.
I recently changed my phone and unfortunately my Secure Sign in app is no longer synced with my NAS. the App is still on my phone yet no account has been configured.
It does, however still generates OTP linked to the Admin account on my NAS.
The issue is that the...
I've got a brand-new NAS running DSM 7.0 and I want to set up 2 Factor Authentication for the admin account. I've done this, and in the setup of 2 factor authentication, it shows a QR code that contains all of the information for the OTP. I easily set this up on my phone, works great.
I have 2FA set up on one of my devices, authenticator app was Google Authenticator. I had to reset my phone due to an issue and spaced about the 2FA on the NAS.
I had email notification set up (2FA setup forces you to do so), but I am not getting any emails when I use the "I lost my phone"...
2FA (two factor authentication) on my RT2600ac is driving me crazy...
every 10 - 15 minutes i have to re input the code generated from my phone
is there a way to trust certain devices, like DSM does, via a cookie?
or there is some menu I am missing so I can add certain devices?
I have a Synology DS216+ that I use in my small business. I am using it as a domain controller with Active Directory Services. I would like to have 2FA when users log in to the Windows 10 PCs. Does anyone know how to do that? I have 2FA enabled on the NAS, but that only deals with native logins...
HI all - loving this unofficial forum, and new NAS DS218+ with DSM 6.2 :)
Would anyone know how to set up multiple-factor authentication for a VPN server (whichever VPN works, really) on DSM, please? Ideally, from most preferred to less preferred:
Hardware token like Yubikey
TOTP like Google...
