Is there a way to set up to go remote on my mom's computer without her having to give me a password

My mom is one state away from me.  She is 90.  I use Team Viewer to go on her computer to fix problems she runs into.  She is going blind and has limited vision.  Is there a way to connect to her computer without her always trying to read the numbers and password for me to gain access to her computer.  She  has to use a large light and huge magnifying glass to read to me and it usually is wrong, especially the password with the mixture of alphabets and numbers.  I usually input the wrong password so many times it throttles me and I have to sit and wait the 30 seconds for her to try to read it again.  Appreciate any help.  Please be explicit if there is a way to do this.  It took me months to get the hang of this program and I am happy with the limited use I understand.  Thanks.
