Cómo recuperar mi contraseña de un archivo

Hi @Liz Noemi21854054sl5d 

Could you please elaborate on the issue a little bit more clearly? As we have understood, it looks like you want to know the password for a PDF file, right?

If so, then the password can only be told by the person who added the password protection to it. 

Here is a help document to know more on how password protection works: https://community.adobe.com/t5/acrobat-reader-mobile-discussions/you-can-now-password-protect-pdf-using-adobe-acrobat-reader-mobile-app/td-p/11508002

Thanks,
