Purple freeze when password added

[Ahmadreza Kermani]

Hey there,

I noticed when I put my password in, the screen freezes on the number of 
circles i put in for password. I wanted to suggest for security, either 
this text input gets empty while the system is processing the password 
or the screen can go all purple. This will make a difference especially 
for slow systems like mine so that people can't see the length of my 
password during lecture or in public or whatever. Thanks.
