Flussonic Default Password File

sudo nano /etc/flussonic/flussonic.conf

Find or add an auth section:

auth 
  admin 
    password = "new_plaintext_password";

Then restart:

sudo systemctl start flussonic

After logging in, you should hash the password via the web UI for security.

auth user admin password = "your_new_secure_password" flussonic default password

Flussonic stores credentials in /etc/flussonic/flussonic.conf (or /opt/flussonic/conf/flussonic.conf).

sudo grep -i "password" /etc/flussonic/flussonic.conf

You may see lines like:

auth 
  user admin 
    password = "your_hashed_or_plain_password";

If the password is hashed (modern versions use bcrypt), you cannot reverse it. If it’s plaintext (discouraged), you’ll see it directly.

During first start, Flussonic generates a random one-time password and writes it to: sudo nano /etc/flussonic/flussonic

/etc/flussonic/flussonic.conf

Look for the line:

password = "randomly_generated_string"

Or check the installation log:

/var/log/flussonic/erlyvideo.log

In very old documentation, you might see references to a default login:

This was used only for initial setup before version 20. Modern installers no longer permit this blatantly insecure default. If you are running an ancient version, upgrading is strongly recommended. Find or add an auth section: auth admin

Flussonic requires explicit authentication setup during installation. If no credentials are configured, the system typically:

With root privileges:

sudo flussonic-cli passwd admin

You will be prompted for a new password. Restart Flussonic:

sudo systemctl restart flussonic

A significant source of "default password" vulnerabilities comes from community-maintained Docker images or deployment scripts found on GitHub.
