Amazon KDP multi-user team login
Amazon KDP sends SMS verification codes to one phone number. Syfon instantly routes that code to your entire publishing team, via SMS, Slack, email, or Google Chat.
Get StartedThe Amazon KDP Login Problem
KDP Has No Team Access
Amazon Kindle Direct Publishing only allows one login per account. Your editors, formatters, cover designers, and marketing team all share one set of credentials.
One Phone Gets Every Code
Amazon requires SMS two-factor authentication. Every login attempt sends a code to one phone. Your team waits, or messages that person every single time.
Book Launches Get Delayed
Need to upload a manuscript, update pricing, or check royalty reports? If the code-holder is unavailable, your entire publishing schedule slips.
Lose the Phone, Lose Access
If that one phone is lost, broken, or stolen, you'll lose access to your KDP account until you can recover it or reset two-factor authentication with Amazon.
With Syfon: Every team member gets the KDP login code the moment Amazon sends it. No waiting. No chasing. No bottleneck.

FAQ: Amazon KDP & Syfon
Is this safe to use with my KDP 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 account in any way. Your Amazon username and password are never shared with or stored by Syfon.
Will this affect my KDP account or royalties?
No. Syfon has no connection to your KDP dashboard, books, 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 KDP and ACX?
If your KDP and ACX 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.
