I play with one finger mostly, but for some faster runs I bring in the middle finger to add a bit more speed, but I don't rely heavily on it. I'm fairly new to Bass as I started in March of this year. I do pretty well with just one finger and have nailed many songs that are played either by Pick or 2 fingers. I see many Bassists using 2 fingers and even 3, and I'm not sure if playing with one finger can be considered a "bad habit". Feedback on this would be most appreciated.
