How do I get rid of the email history on tumblr?

[Eliza]

I feel your pain do this to often
any way what you do is go into your chrome web history
at the top you will see an option that says "clear browsing data" click on that
at the top of this it will say "Obliterate the following items from" choose how far back you want delete depending on when put your password in the email section
following this a list of things will come up tick the one that says "clear saved autofill form data" and that should do it

hope this helped
