Is there a way to "toggle" between two completely separate Trello accounts? For instance, I have one for Work and one for Personal. NOT separate boards, but actually separate accounts. I don't want the two to "talk" to eachother/be linked necessarily. I just want to be able to do something like click on my work user name at the top right and then select my personal user name to toggle to that trello account. Then be able to go back to my work one WITHOUT having to log out/in or use another tab/browser/incognito tab.
Is it currently possible?
Sadly, this is not currently possible. My best workaround suggestions are to use Chrome profiles to sign into both accounts, or to share the boards you need to access with both accounts, so you can edit your work boards from your personal account and vice versa. Sadly, these are workarounds and not the ideal solution you propose. I would advise you to submit this as a feature request to Trello Staff through this link. It's a great feature idea :)
I wish I had a better answer for you, but I hope you're able to find a solution that works in the interim!
