Hi @courageous_vibrancy4453
I hope you are doing well, and thank you for reaching out. I'm sorry you are dealing with this, and it makes sense that you want to secure your account.
For your Adobe account, these steps can help:
Change your Adobe password from the Sign-in and security page at https://adobe.ly/4xRlbqO. When you change it, select the option to sign out of your active logins, so any device still signed in to your account, including the one that was sold, is signed out. Steps are here: Reset or change Adobe password.
On the same page, turn on two-step verification and choose your preferred method (Adobe Account Access app, email, or text message). This adds a verification code on top of your password. Make sure the email address and phone number you use for verification are ones only you can access. Steps are here: Set up two-step verification.
Let us know how it goes, and we're here to help if you need anything else.
Regards,
Amal
