How alternate account detection works
People often mix up VaultCord alt detection, Discord bans, VPN blocking, and blocklists. They are different systems. This guide explains what each one does.
Settings live under Servers → Settings → Security (and Firewall for blocklists/allowlists). Many protection features need a paid plan.
Quick comparison
System | What it checks | What it can do |
Alt account detection (VaultCord) | Same IP as another member already verified on your VaultCord server | Log a warning, block the verified role, and/or ban in your Discord server |
Block VPN / mobile (VaultCord) | VPN / proxy / cellular networks | Block verify |
Your Firewall blocklist | Rules you add (Discord ID, IP, country, provider, etc.) | Refuse verify; optionally auto-ban if you enable that |
Allowlist | People/networks you allow | Let them verify and bypass alt & VPN checks |
Block scammers (ScammerAlert) | Discord user IDs on the ScammerAlert list | Block verify |
Discord’s own bans / ban evasion | Discord’s platform rules when someone is banned on Discord | Separate from VaultCord; Discord decides that |
VaultCord does not use Discord’s global “Trust & Safety ban list” as its alt detector. Alts are detected from your verify data (mainly matching IP on your server).
1. VaultCord alternate account detection
How it works
When someone verifies, VaultCord can look for another member on the same server who already verified with the same IP, but a different Discord account.
If a match is found, your verify logs can show something like “Alt account detected” (the member usually isn’t told in that log title).
Your three alt switches (Security settings)
Alt account detection
Turns detection/logging on.Don’t give role to alts
Turns detection into a block: they don’t get the verified role.
Leave this off if you only want a warning in logs (some owners still give roles because the “alt” may be an old account).Automatically ban alt accounts
VaultCord’s bot bans them in your Discord server, with an audit reason that they look like an alt of another user.
You can turn this off under Security → “Automatically ban alt accounts.”
Allowlist override
If the user (or their IP / region / country / provider) is on your allowlist, VaultCord will not block them for alts—even if detection would otherwise flag them. Allowlist tooltip text: bypass alt account & VPN checks.
Limits (honest)
Matching is based on IP among members already in your VaultCord data for that server.
Shared Wi‑Fi (family, school, work, campus) can flag false positives.
Different IP / VPN can miss alts.
This is not the same as Discord’s ban-evasion system.
2. Discord bans (your server vs Discord platform)
Bans inside your Discord server
You (or mods) ban someone in Discord → that’s Discord’s ban list for your server.
VaultCord Automatically ban alt accounts also creates a server ban when an alt is flagged.
That does not mean Discord globally banned them everywhere.
Discord ban evasion (platform)
If Discord terminates or bans an account, Discord may flag other accounts used from the same device/IP as ban evasion. That’s Discord’s system. VaultCord’s alt tools are separate and only apply at verify time on your VaultCord server settings.
3. ScammerAlert (not Discord’s ban list)
Block scammers from verification checks a partner list (ScammerAlert, 13.4K+ listed users).
If enabled and the Discord user ID is on that list, VaultCord blocks verification and can log that they were banned on ScammerAlert—not that Discord’s global ban list was queried for alts.
4. Firewall blocklist & allowlist
Under Servers → Settings → Firewall:
Blocklist — your rules (Discord ID, IP, fingerprint, region, country, ISP/ASN, etc.). With Refuse blocklisted members, matching users can’t verify. Optional auto-ban blocklisted users bans them in Discord when they match at verify time (it does not ban everyone the moment you add a rule).
Allowlist — trusted exceptions; can bypass alt & VPN checks.
These are your lists, not Discord’s.
5. VPN / mobile blocking (related, but not “alts”)
Block VPN networks — blocks verify when a VPN/proxy is detected.
Block wireless mobile networks — blocks many LTE/5G connections.
Someone on a VPN might look like a different person to IP-based alt detection, or get blocked by VPN rules first. Don’t confuse “VPN blocked” with “alt detected.”
Recommended setup (typical)
Goal | Turn on |
Only get notified of possible alts | Alt account detection |
Stop alts from getting the verified role | Detection + Don’t give role to alts |
Ban alts in Discord automatically | Detection + Automatically ban alt accounts |
Let staff / family on shared Wi‑Fi verify | Add them to Allowlist |
Block known scammers | Block scammers from verification |
Block specific IDs/IPs/countries | Firewall blocklist |
Common confusion
“Discord already banned them—why did VaultCord let an alt verify?”
Discord’s ban on one account doesn’t automatically feed VaultCord’s alt detector. VaultCord only flags alts when its own rules match (usually same IP on your server), unless you also use blocklist / ScammerAlert / Discord ban manually.
“Someone on the same Wi‑Fi got flagged as an alt.”
Expected with IP matching. Use Allowlist for people you trust.
“Alt detection is on but they still got the role.”
You need Don’t give role to alts (and/or auto-ban). Detection alone mainly logs.
