man sshd:
~/.ssh/authorized_keys
Lists the public keys (DSA, ECDSA, Ed25519, RSA) that can be used
for logging in as this user. The format of this file is
described above. The content of the file is not highly sensi‐
tive, but the recommended permissions are read/write for the
user, and not accessible by others.
If this file, the ~/.ssh directory, or the user's home directory
are writable by other users, then the file could be modified or
replaced by unauthorized users. In this case, sshd will not
allow it to be used unless the StrictModes option has been set to
“no”.
