Short answer: buy a NIKKE account on the server you play, with the login it is bound to (a Level Infinite Pass email, or a Google, Apple, Facebook, X or Line account) handed over with its email, and never a guest account. A direct store such as METAMMO sells to you itself, checks every account by hand and covers it for life against recovery by a previous owner; escrow marketplaces such as G2G, Eldorado and PlayerAuctions host many sellers and cover you for days or weeks. The publisher's licence agreement forbids selling or sharing an account, so no seller can promise the account will never be banned.
Marketplace terms below come from each platform's own help pages, checked 6 October 2026. NIKKE facts come from the publisher's licence agreement and privacy policy. This guide was updated on 20 October 2026.
Store or marketplace: what is the difference?
On a marketplace you buy from one of many sellers. The platform does not own or check the account; it holds the payment, takes a fee and settles disputes within its cover period. Quality depends on the seller you happen to pick, and the same account is often listed by several resellers at once.
With a direct store there is one seller: the store. It sources the account, checks it by hand and answers for it after the sale. What you give up is third-party escrow, so look at the store's public record before you pay. METAMMO's record is public on G2G, Eldorado and GameBoost.
Which login holds a NIKKE account
NIKKE's privacy policy lists the ways to sign in: guest, Facebook, Google, Twitter, Line, Apple and Level Infinite Pass, which uses a username and email. Level Infinite Pass is the publisher's system to unify its games' accounts under one login. Whatever the account is bound to is the account: a seller who keeps that Google or Apple account, or the Level Infinite Pass email, can sign back in.
Guest accounts are the weakest kind. The publisher keeps device data only to help guests who lost their account, and a guest account has no login to hand over. Ask which server the account is on, too: NIKKE runs separate regional servers, and a strong account on one server does nothing for you on another.
What the rules say
NIKKE's End User License Agreement says you may not sell, resell, rent, lease, share or provide access to your game account to anyone else, forbids secondary markets for virtual goods and lets the publisher suspend or terminate access for a breach. No seller can remove that risk.

Platform-wide account terms from each platform's own help pages, checked 6 October 2026; they apply to any NIKKE account bought there. Other sites such as Z2U, EpicNPC and FunPay also carry game account listings; we have not compared their terms here. Dispute handling and seller checks are compared in our marketplace comparison.
Every marketplace above holds your payment until delivery, which protects you against a seller who never hands over the login. Their cover then runs for a fixed period, while a recovery by a previous owner can come months later. That gap is why the length of cover matters as much as having cover at all.
What to check before paying
- The bound login. Level Infinite Pass email or the social account, handed over with its email.
- Not a guest account.
- The server. The one you play on.
- Units, limit breaks and cores in game. A screen recording of the Nikke list sorted by rarity, with the commander ID visible.
- Gems and pulls. Gems and Recruit tickets in the title are claims until you see them in a current recording.
Red flags
- A guest account, or a seller who offers only an in-game ID.
- A Google or Apple login the seller will not hand over.
- Unit lists typed into the title with no recording.
- A request to pay outside the marketplace to save fees.
- A promise that the account cannot be banned.
How METAMMO handles NIKKE accounts
METAMMO is a store, not a marketplace: you buy every account from METAMMO, not from an individual seller, and each one is checked by hand: the server, bound login, units and gems match the listing. So the deal and the recovery risk are ours. Our warranty is lifetime and covers one thing: if a previous owner ever takes the account back, you get a replacement of equal value or a full refund, your choice. Bans by the publisher are not covered, because no seller controls them.
We have sold game accounts for years and know how the publisher's rules and bans work, so we tell you what to avoid. Delivery is usually within minutes to a few hours, at most 24, with help moving the email and logins to yours. If the account you want is not listed, tell us the server and units you want and we look for one.

Frequently asked questions
Where is the safest place to buy a NIKKE account?
A seller that hands over the bound login with its email, on the server you play, and covers recovery for longer than a few days. METAMMO is a store: you buy from METAMMO, every account is checked by hand and carries a lifetime warranty against recovery by a previous owner.
What is Level Infinite Pass?
The publisher's account system that unifies its games under one login with a username and email. If a NIKKE account is bound to it, you need that email.
Should I buy a guest NIKKE account?
No. A guest account has no login to hand over and is the hardest to keep.
Is buying a NIKKE account against the rules?
Yes. The licence agreement says you may not sell or share your game account. METAMMO's warranty covers recovery by a previous owner, not bans.
