PASSWORD NEVER WORKS

I have a love hate relationship with your software Login. I like the platform, but I never can get my password to be accepted. I reverted to using the most simple passwords without any type of caps, etc. and wrote them down as large as life to make sure I am not crazy. Still it doesn’t matter the blog im trying to access, where I am at ( I have 3 separate places and systems to access my blogs), I STILL CANT GET IN. Everytime I have to reset my passwords and then it WP lets me in for like 1 or 2 sessions and then rejects the password again. this happens on every blog i own.

what can i do??????
