换手机时，如何迁移 Steam 令牌
换手机前，先确认自己有可用的令牌备份，还是需要通过 Steam 转移令牌。导入备份、转移和移除令牌是不同操作，对交易的影响也不同。
选择迁移方式
- 已有 SDA、AVA 或 Steam++ / Watt Toolkit 导出的
.maFile：可以导入新设备，沿用同一令牌，无需重新绑定。交易限制以 Steam 提示为准。 - 没有备份：在新设备上登录，按提示转移令牌。Steam 的转移流程会带来 2 天交易和市场限制。
- 无法转移，也没有可用备份：通过 Steam 客服恢复账户。移除令牌会带来 15 天交易和市场限制。
为什么会有交易限制
Steam Guard 用于保护账户登录和库存交易。转移或移除令牌后，Steam 会暂时限制交易和社区市场操作，给账户所有者留出处理异常的时间。
Steam 的转移流程有 2 天限制；移除令牌有 15 天限制。导入已有 .maFile 则是恢复同一份令牌密钥，不需要移除或重新绑定。账户若已有其他限制，导入备份不会解除它们，具体时间请查看 Steam 提示。
三种方式对照
| 方式 | 交易限制 | 需要准备 |
|---|---|---|
| 通过 Steam 转移令牌 | 2 天 | 账户登录和 Steam 要求的验证方式 |
导入已有 .maFile | 无需重新绑定；以 Steam 提示为准 | 可用的令牌备份 |
| 移除后重新绑定 | 移除会限制 15 天 | 撤销码，或通过 Steam 客服完成账户验证 |
方式 A：转移令牌
AVA 提供令牌转移入口。开始前，请确认能登录账户，并能完成 Steam 要求的验证。
- 在新设备上安装 AVA，登录 Steam 账户。
- 账户已有令牌时，选择「把令牌迁移到本设备」。
- 按提示完成验证；如果提示发送了邮件，请输入账户邮箱收到的验证码。
- 确认转移，并保存新显示的撤销码。
旧手机不一定需要在手边，但必须能完成当前流程要求的验证。开始前检查账户绑定的邮箱和手机号是否仍可使用。
确认前需要知道
- 转移成功后，旧设备的令牌立即失效。
- 撤销码（
Rxxxxx）会更新，旧码作废。新码只显示一次，请在离开页面前保存。 - 确认后的变更不可撤销，交易和市场限制以 Steam 显示的时间为准。
设备丢失时，可以用撤销码移除令牌。请将它保存在手机以外的安全位置，以免设备和恢复凭据一起丢失。
方式 B：导入已有 maFile
如果令牌保存在 Steam Desktop Authenticator、Steam++ / Watt Toolkit 或 AVA 中，可以导出 .maFile 并导入新设备。
- 在旧设备上导出或找到对应账户的
.maFile。 - 在新设备的 AVA 中导入，核对账户信息。
导入会沿用文件中的令牌密钥，无需移除或重新绑定令牌。账户也可以在 AVA 和 ArchiSteamFarm 等工具中使用同一份密钥。会话登录或交易操作仍可能需要连接 Steam，已有交易限制不会因导入而解除。
.maFile 是明文文件，包含 Steam Guard 密钥和撤销码。拿到文件的人可以使用你的令牌。请按密码保管：不要发到聊天里、放进共享盘，或上传到声称能「验证」文件的网站。
不要把文件交给陌生人、交易平台或自称客服的人。即使是你自己部署的工具，也应确认它的来源和密钥存储方式。
建议在旧设备仍可使用时导出备份，并确认备份保存在安全、找得到的位置。
方式 C：移除后重新绑定
如果无法转移，也没有可用备份，可在 Steam 中进入「客服 → 帮助 → Steam 令牌」，按提示恢复账户。客服可能要求验证账户所有权。移除令牌会触发 15 天交易和社区市场限制。
重新添加的令牌还需满足 Steam 的启用时长要求：使用移动令牌确认交易，通常要求令牌已启用至少 7 天。不同限制可能同时存在，请以账户页面显示的时间为准。
备份和账户安全
- 撤销码截图可能自动同步到云相册。保存前检查同步设置，避免恢复凭据意外上传。
- 不要将
.maFile发给他人，它包含令牌密钥。 - 转移成功后旧令牌会失效，清空旧设备前先确认新设备能正常使用。
- 尽量在旧设备仍能开机时完成备份和迁移。
常见问题
一定需要旧手机吗？
不一定。能否转移取决于你能否完成 Steam 当前要求的验证；已有可用 maFile 时也可以直接导入。
收不到验证邮件怎么办？
先检查垃圾邮件，再核对 Steam 账户绑定的邮箱。若已无法使用该邮箱，按 Steam 页面提示尝试其他验证方式或联系 Steam 客服。
能管理多个 Steam 账户吗？
可以。AVA 在手机和桌面上都支持多个账户，各自显示验证码、交易确认和报价。官方 Steam App 也支持添加多个账户。
AVA 是官方应用吗？
不是。AVA 是以 MIT 协议开源的社区项目，与 Valve 和 Steam 没有隶属关系。账户操作仍由 Steam 验证和处理。
这些功能收费吗？
验证码、交易确认、登录批准、令牌迁移，以及 .maFile 导入导出，在所有版本中均免费，并会继续免费提供。付费档解锁两套皮肤并去除广告。也可以自行编译不含广告与计费代码的版本。

Move your Steam Guard authenticator to a new phone
Before changing phones, check whether you have an authenticator backup or need to transfer it through Steam. Restoring a backup, transferring, and removing an authenticator are different operations with different trading restrictions.
Choose a method
- Have a
.maFileexported from SDA, AVA, or Steam++ / Watt Toolkit? Import it on the new device to keep using the same authenticator. No re-enrollment is needed; check Steam for any account restrictions. - No backup? Sign in on the new device and follow the transfer prompts. Steam's transfer process brings a 2-day trading and market restriction.
- Unable to transfer, with no usable backup? Recover the account through Steam Support. Removing an authenticator brings a 15-day trading and market restriction.
Why trading restrictions apply
Steam Guard protects account sign-ins and inventory transactions. After a transfer or removal, Steam temporarily restricts trading and Community Market access to give the account owner time to respond to unexpected changes.
See Steam's official guidance on authenticator transfers and removing an authenticator.
Steam's transfer process has a 2-day restriction; removing the authenticator has a 15-day restriction. Importing an existing .maFile restores the same secret without removal or re-enrollment. Restoring a backup does not lift other account restrictions. Check the timing shown by Steam.
Compare the methods
| Method | Trading restriction | What you need |
|---|---|---|
| Transfer through Steam | 2 days | Account access and the verification Steam requests |
Import an existing .maFile | No re-enrollment; check Steam for restrictions | A usable authenticator backup |
| Remove and re-add | Removal restricts trading for 15 days | A revocation code or account verification through Steam Support |
Method A: transfer the authenticator
AVA includes an authenticator transfer option. Before starting, make sure you can sign in and complete the verification Steam requests.
- Install AVA on the new device and sign in to your Steam account.
- For an account with an existing authenticator, select “Move the authenticator to this device.”
- Complete the verification prompts. If Steam sends an email, enter the code from your account inbox.
- Confirm the transfer and save the new revocation code.
The old phone is not always required, but you must be able to complete the verification requested by the current flow. Check that the email address and phone number on the account are still accessible before starting.
Before you confirm
- After a successful transfer, the old device's authenticator stops working immediately.
- The revocation code (
Rxxxxx) changes and the old one expires. The new code is shown once; save it before leaving the screen. - The confirmed changes cannot be undone. Check Steam for the end time of trading and market restrictions.
A revocation code can remove the authenticator if your device is lost. Store it somewhere safe outside the phone, so losing the device does not also mean losing your recovery details.
Method B: import an existing maFile
If your authenticator is stored in Steam Desktop Authenticator, Steam++ / Watt Toolkit, or AVA, you can export its .maFile and import it on the new device.
- Export or locate the account's
.maFileon the old device. - Import it into AVA on the new device and check the account details.
Importing keeps the same authenticator secret, without removal or re-enrollment. The same secret can also be used in AVA and tools such as ArchiSteamFarm. Session sign-in and trading can still require a connection to Steam, and importing does not remove existing trading restrictions.
A .maFile is a plain-text file containing the Steam Guard secret and revocation code. Anyone with the file can use your authenticator. Treat it like a password: do not send it in chats, put it on shared drives, or upload it to a website offering to “verify” it.
Do not give the file to strangers, trading platforms, or people claiming to be support staff. Even with tools you host yourself, check where the software comes from and how it stores secrets.
Export a backup while the old device still works, and make sure you can find it in a secure location.
Method C: remove and re-add
If you cannot transfer and have no usable backup, go to Steam's Support → Help → Steam Guard section and follow the account recovery prompts. Support may require proof of ownership. Removing the authenticator triggers a 15-day trading and Community Market restriction.
A newly added authenticator must also meet Steam's activation requirement: using mobile confirmations for trading normally requires it to have been active for at least 7 days. Restrictions can overlap; follow the timing shown on your account.
Backups and account security
- A screenshot of the revocation code may sync to a cloud photo library. Check your sync settings before saving recovery details this way.
- Do not share your
.maFile; it contains the authenticator secret. - The old authenticator stops working after a transfer. Check that the new device works before wiping the old one.
- Back up and transfer while the old device can still turn on.
Common questions
Do I need the old phone?
Not always. A transfer depends on completing the verification Steam currently requests. You can also import a usable maFile backup.
What if the verification email does not arrive?
Check spam, then confirm which email address is linked to Steam. If you no longer have access, follow Steam's prompts for another verification method or contact Steam Support.
Can I manage multiple Steam accounts?
Yes. AVA supports multiple accounts on mobile and desktop, with separate codes, confirmations, and trade offers. The official Steam app also supports adding multiple accounts.
Is AVA an official app?
No. AVA is a community project, open source under the MIT license, with no affiliation to Valve or Steam. Steam still verifies and processes account operations.
Do these features cost anything?
Codes, trade confirmations, sign-in approval, authenticator transfer, and .maFile import and export are free in every build and will remain free. The paid tier unlocks two skins and removes ads. You can also compile a version without ad or billing code.
