My understanding is this is a limitation of the interface, which needs to do several rounds of crypto computations, and sadly is not a supercomputerLogin before unlocking takes 10-20 seconds. I am not sure if it can be improved, if not this is it, 10-20 second extra is not a problem.
. On the plus side, like you said, 20 seconds give you a 30 minute session, so in that context, I think it's reasonable.Might I recommend a password manager? I use 1Password, but if you want a free option I'd probably suggest Bitwarden.I have been using the beta for the past couple of weeks and no issues to report other than entering my password wrong on a couple of occasions as I have too many to remember.
I'm really pleased a native unlock has finally been added as its easier and faster to use than logging into ODIS. Would be great if the "session" could be extended from 30 minutes to 60 / 1 hour.
Not a complaint, just a curiosity... how come the sessions are 30 minutes when a module's unlock lasts 90 minutes?My understanding is this is a limitation of the interface, which needs to do several rounds of crypto computations, and sadly is not a supercomputer.

I’m of no authority to state the exact reason why - but it makes logical sense that a finite time span for data input requests presents finite opportunities for digital safety risks, exploitation, expensive mistakes and “poke around until something happens” level workmanship.Not a complaint, just a curiosity... how come the sessions are 30 minutes when a module's unlock lasts 90 minutes?
It's intentionally a bit on the short side for Beta testing purposes. I actually agree that it could be lengthened and might well be when we go to full Release. That said, 30 minutes is enough time to go and manually unlock every module that has SFD in a in a high-spec 2026 car -- I've done personally done this with time to spare. And for normal service operations, it should not be necessary to unlock more than two or three modules.how come the sessions are 30 minutes when a module's unlock lasts 90 minutes?
When these [SFD2] prefixes are shown? I tried a SFD2 protected car with the lates VCDS version and there were no prefixes like in this attachment.
What car? What module? Was the Gateway unlocked and the filter de-activated?I tried a SFD2 protected car with the lates VCDS version and there were no prefixes like in this attachment.
I get what you're saying but I would argue just having an open SFD session isn't really like disabling a firewall, I think it's more akin to logging in to an admin account. Basically, you have the key to disable the firewall but haven't necessarily done so.I’m of no authority to state the exact reason why - but it makes logical sense that a finite time span for data input requests presents finite opportunities for digital safety risks, exploitation, expensive mistakes and “poke around until something happens” level workmanship.
In my case, I’m currently awaiting my VCDS SFD service account activation confirmation to come through. I have a small but critical laundry list of values to address and have the guides hot and ready to go which 30 minutes really should be ample.
SFD is often referred to as a firewall, and I’m certain I would not want my home network firewall disabled for more than a few minutes since it is against best practice and carries unnecessary risk.
Copy that, thanks.It's intentionally a bit on the short side for Beta testing purposes. I actually agree that it could be lengthened and might well be when we go to full Release.

Because they're not directly related. You need a SFD session to unlock a module, but the SFD session doesn't need to continue for the module to stay unlocked. What do you feel would be gained by making the SFD session 90 minutes?how come the sessions are 30 minutes when a module's unlock lasts 90 minutes?
I see you did change some of both . Does that stay permanently at zero or was it a glitch that disappears if you test the interface again? I just checked with my SFD2 gateway here and the adaptation number increases when I turn off the filter.I noticed the "About" panel shows zeros for both the number of codings changed and adaptations saved
I'm not asking for it to be increased, I'm ok with either length; I just figured there was probably a reason they weren't the same so I was curious.
I'll try to check over the weekend.I see you did change some of both . Does that stay permanently at zero or was it a glitch that disappears if you test the interface again? I just checked with my SFD2 gateway here and the adaptation number increases when I turn off the filter.
I just opened my computer and connected the cable to my car; VCDS was still open. I checked the "About" panel and now it shows three codings changed and seven adaptations saved. I tested the interface then checked "About" again and neither value changed. I quit VCDS, reopened it, and the values were the same.I see you did change some of both . Does that stay permanently at zero or was it a glitch that disappears if you test the interface again? I just checked with my SFD2 gateway here and the adaptation number increases when I turn off the filter.
