Hi @different_critic429a
I hope you are doing well, and thanks for reaching out.
Could you please confirm:
Whether you mean your saved signature or initials, or your account sign-in (such as the email or name shown in the app).
Whether you use Android or iPhone, and the Adobe Scan app version.
Where in the app you see it (for example, when you open a scan and select Fill & Sign).
If you mean a saved signature, you can read more about signing on mobile here: https://adobe.ly/47G5x73
Let us know how it goes.
Regards,
Amal
