ACX publisher team login is here
ACX uses Amazon's single login with SMS two-factor authentication. Syfon instantly routes that verification code to your entire audiobook production team, via SMS, Slack, email, or Google Chat.
Get StartedThe ACX Login Problem
ACX Has No Team Access
ACX uses a single Amazon login. Your narrators, producers, proofers, and rights holders all share one account, with no way to add team members.
One Phone Gets Every Code
Amazon requires SMS two-factor authentication for ACX. Every login sends a code to one phone. Your team waits, or messages that person every single time.
Audiobook Production Stalls
Need to approve a final audio file, check royalty splits, or respond to an ACX review? If the code-holder is unavailable, your production timeline slips.
Lose the Phone, Lose Access
If that one phone is lost, broken, or stolen, you'll lose access to your ACX account until you can recover it or reset two-factor authentication with Amazon.
With Syfon: Every team member gets the ACX login code the moment Amazon sends it. No waiting. No chasing. No bottleneck.

FAQ: ACX & Syfon
Is this safe to use with my ACX account?
Yes. Syfon only receives the SMS verification code that Amazon sends and forwards it to your team. It does not interact with your Amazon or ACX account in any way. Your Amazon username and password are never shared with or stored by Syfon.
Will this affect my audiobooks or royalties?
No. Syfon has no connection to your ACX dashboard, audiobooks, or royalties. It simply routes the SMS verification code so your team can log in. Everything else works exactly as before.
How fast do codes arrive?
Codes are forwarded in seconds, fast enough to use before they expire. Your team won't notice any delay compared to receiving the SMS directly.
Can I use this for both ACX and KDP?
If your ACX and KDP accounts use the same Amazon login, one Syfon number covers both. If they're separate accounts, you can get a number for each.
How long does setup take?
Once you sign up, we carry out some manual checks to ensure the service is not being used for spam purposes. Usually your number is available the same day. After that, just update your SMS number in your Amazon settings and log in to your Syfon account to choose where to route codes.
Is there a free trial?
Unfortunately, we can't offer a free trial as the phone number incurs a monthly rental fee. But you can try Syfon for one month and cancel at any time. No lock-in.
