Make the password uppercase. An old man who does not know English, sees the password in lowercase, and can not dictate. Since the keyboard only uppercase.
Thank you for your message.
In that case, I recommend you to set up a 4-digits password.
You go to : Extras → Security → Random password
And set up Standard (4digits). Numbers will be displayed, it will be way easier for the old man.
I hope this could help. If not, do not hesitate to contact us again.
