I use mongo so I have to follow a different approach to unlock my account
launch your mongo cli, switch to the nodebb db and run

db.objects.remove({"_key":"lockout:YOUR_UID"})

uid is usually 1 for admin

If you don't know what your uid is you can run

db.objects.remove({"_key": { $regex: /lockout:.*/ }})

to unlock all locked accounts

Becareful when doing this as I'm not sure if it would have any other side effects I'm not aware of. It's only meant to be a quick way restore order if you keep locking yourself out during dev
