Free Password Generator by NexLink Core
The NexLink Core Password Generator creates strong, genuinely random passwords for every account tied to your server — game panel logins, RCON, FTP/SFTP, databases, and admin accounts.
Choose between a fully random password, a memorable passphrase built from real words, or a numeric PIN.

Why Random Passwords Matter for Game Servers
Game servers are a constant target for automated attacks. Most break-ins are not clever — they are bots working through lists of leaked and predictable passwords until something opens.
A randomly generated password defeats this because there is no pattern to guess:
- No dictionary words — a password built from random characters can’t be found in a wordlist.
- No personal information — server names, game names, and birth years are the first things attackers try.
- No reuse — a unique password per service means one leaked credential can’t be replayed against your panel, your database, and your billing account.
Generate a separate password for every service. If you run five servers, that’s five RCON passwords — not one shared across all of them.
Choosing a Password Length
Password strength is measured in bits of entropy — roughly, how many guesses an attacker needs. Each extra character adds significantly more work for an attacker, which is why length matters more than exotic symbols.
| Use case | Recommended length |
|---|---|
| RCON, FTP/SFTP, database accounts | 20–32 characters |
| Game panel and billing logins | 16–24 characters |
| Service accounts you never type by hand | 32+ characters |
| Passwords you must type into a game console | 16 characters, look-alikes excluded |
The generator shows an entropy estimate as you adjust the options. As a rule of thumb, anything at or above 80 bits is comfortably out of reach of brute-force attacks with current hardware.
Excluding Look-Alike Characters
Some characters are hard to tell apart in server console fonts — capital I, lowercase l, and the digit 1, or capital O and the digit 0. Enable Exclude look-alikes when you know you will have to read a password off a screen and type it in manually.
This slightly reduces the character pool, so add a few characters to the length to compensate. The entropy readout updates automatically so you can see the trade-off.
Symbols and Compatibility
Symbols increase strength, but some systems handle them badly. A few things to watch for:
- Passwords placed in a config file may break if they contain characters the file format treats specially — always quote the value where the format allows it.
- Passwords passed on a command line can be mangled by the shell. On Linux, wrap the value in single quotes.
- Some game panels and databases restrict which symbols are accepted. If a password is rejected, turn symbols off and add 4–6 characters to the length instead — the result is still strong.
Never paste a server password into a public Discord channel, a support ticket, a screenshot, or a pastebin. If a password has been shared anywhere you don’t fully control, rotate it.
Storing Your Passwords
Strong random passwords are impossible to memorise, and that’s fine — they aren’t meant to be memorised.
- Use a password manager. Bitwarden, 1Password, KeePassXC and similar tools store credentials encrypted and fill them for you.
- Never store passwords in plain text — not in a
.txtfile on the desktop, not in a pinned Discord message, not in a spreadsheet shared with your staff team. - Share access, not passwords. For staff who need panel access, create a subuser account for each person instead of handing out the owner credentials. You can then revoke one person’s access without resetting everything.
- Rotate after staff changes. When an admin leaves your community, rotate every credential they had access to.
Our game panel supports subusers with granular permissions. See Adding Subusers to give your staff access without sharing your own login.
Frequently Asked Questions
How random are the passwords?
Every character is chosen with a cryptographically secure random number generator, combined with rejection sampling so that each character in the pool is equally likely. This is the same class of randomness used for encryption keys — not the predictable Math.random() used by many online generators.
Which mode should I use?
Use Random for anything a password manager will fill for you — it packs the most strength into the fewest characters. Use Memorable when a human has to read the password aloud or type it from a note. Use PIN only where a service accepts nothing else.
Are memorable passphrases weaker?
Only per character, not per password. A passphrase gets its strength from the number of possible word combinations, so it needs to be longer to match a random string. The entropy readout tells you exactly where you stand — add a word or two until you clear 80 bits.
Can I generate passwords for my whole staff team at once?
Yes. Use the Bulk Generate section to produce up to 50 passwords at a time using the same settings, then copy the whole list.
What should I do if a server password leaks?
Change it immediately, then check for anything the attacker could have left behind — unfamiliar admin accounts, changed permissions, or unexpected scheduled tasks. If you host with us and suspect a compromise, open a ticket and our team can help you audit the server.
