Amazon account hacked twice in 2 weeks - how do I stop it from happening again?

**Help: My Amazon account keeps getting hacked - what am I missing?**

I'm getting repeatedly compromised on my Amazon account and I need help figuring out why this keeps happening.

**Timeline:**

- First hack: Discovered unauthorized access to my account

- Immediately changed password to a new, strong unique password

- Two weeks later: Account compromised AGAIN

**What I know:**

- Both hacks happened with different passwords (new password was never used anywhere else)

- I was able to recover both times and regain access

- No fraudulent charges (yet), but activity shows logins from unknown locations

**What I've checked so far:**

- Password was unique to Amazon, not reused anywhere

- Haven't noticed obvious malware on my devices

- Haven't checked for connected third-party apps yet

**My theories:**

- Malware on one of my devices capturing login info?

- They have my recovery email/phone and are resetting the password that way?

- Malware installed during first breach that I haven't removed?

- Connected apps I don't know about still having access?

**What I want to do:**

1. Stop this from happening a third time

2. Secure my account permanently

3. Figure out if this is a device problem or account problem

Has anyone dealt with this pattern? What am I missing? Any advice on the best next steps?

Thanks in advance.
