I use steemauto.com for all of the accounts I have control over currently. It is a nice tool and functions well most of the time best of all it is free. Although you can donate to the cause.

It only uses posting key to log in with steemconnect but to authorise it you have to use your active key one time.

I only use the claim rewards tool and the fanbase part of it. It a list where you create the accounts to vote on how many per day and what percentage of vote you use per account.
Its pretty easy to set up.
The only thing I would prefer it had was a option to upvote comments. I have a few great friends on here that only comment. I always have to manually upvote them. I hate it when I miss voting for them. As well It would be nice to have a flag option to automatically flag people too.

@lovenfreedom is working on some code to make our own system. When she gets it done and tweaked we will allow others to use it.
