When inserting (pasting) a public SSH key on a user’s folder, within a Droplet, Im seeing a lot of people urge to
chmod 700 ~/.ssh
and then to
chmod 600 ~/.ssh/authorized_keys
But if i chmod 600 ~/.ssh/authorized_keys with my user then i am not able to login via ssh, i need to change it to chmod 755 ~/.ssh/authorized_keys in order to connect.
Which leads to my question: Why is so important to have a public key under chmod 600??
And why im not being able to connect with chmod 600 but only with chmod 755?
Thanks in advanced

Ok to answer my own question i was not able to SSH with my user cause i needed to make sure that user owned the files and folders and not root, with:
where user = myusername
But i still don’t understand why a public key needs chmod 0600
