Only if your looking to find OEM service / repair info or do reprogramming.
I'm sure the whole things a bit of a revenue raiser and just making some cushy jobs. Not sure what the $99/year membership gets you - other than being "accredited" so you can then go and purchase the service or reprogramming subscription separately (which is what you actually wanted to start with). Some of the OEM portals use your AASRA login details to login, but others you have to create a separate account.
You've got to download the AUTHY app on your phone for 2FA - it's not optional, can't use google authenticator or whatever token generating app you use for everything else (I emailed them and tried), has to be AUTHY. I'm sure there's criminals everywhere out there waiting to hack into my AASRA account so they can use it for a whole lot of nothing.
There's a similar setup in the states that the AASRA is based off - the NASTF ( https://wp.nastf.org/?page_id=3969 ). Standard membership over there is free, and I'm sure the whole system probably works better as well.
EV accreditation is pretty well necessary for most current model stuff. The OEM's worked out they can lock up the whole service manual if there's a section in it relating to anything high voltage. You won't get anything for a Camry, Corolla, Rav4, even if its a straight petrol one, because they had hybrid options. Same will be true now for current model Hilux.
Some of the stuff has actually became harder and more expensive to access than it was before (eg. GM ACdelco website or Toyota manuals). And every portal is different - you have to work out how to use them.
The only advantage is it applies to all makes and models - so you CAN get the information if you really really need it.
In the real world though I rarely use it. It would be a last resort to find some information, only if it wasn't readily available elsewhere and I really had to have it. Most people I know in the industry aren't members.
