TikTok Account Guide: Sign-Up, OTP & Recovery

Sign up with a phone number

TikTok's own help keeps it short: download the app from the App Store or Google Play, open it, choose a sign-up method, then follow the steps [S1]. On a computer, the same choice sits behind Log in, then Sign up at the bottom of the window.

Tap Sign up, then Use phone or email.

Stay on the Phone tab and pick the correct country code first — a wrong code is the most common reason the text never arrives.

Type your number, tap Send code, and enter the code from your messages.

Enter your real birthday, set a password, and pick a username.

One rule shapes everything after this. Each phone number, email address and social media account links to one TikTok account only [S1][S2]. That number is now your way back in, and losing access to it makes recovery slow — TikTok's reset-authentication route can take up to 30 days [S2].

Sign up with email instead

You do not need a phone number to join TikTok. Choose Use phone or email, switch to the Email tab, and type an address you can open right now — not one you will abandon. TikTok emails you a verification code; enter it, set a password, enter your birthday, pick a username. Done.

If privacy is why you are reading this, sign up with email. A phone number on the account lets TikTok suggest your profile to people who have your number saved, once contact syncing is on [S2]. An email-only account sidesteps that path. The trade-off is real: TikTok recommends adding a phone number so you can get back in if you lose access to your email [S2]. So sign up with email, then add your own long-term number under Profile, Menu, Settings and privacy, Account, Account Information, Phone number [S2].

Social logins work too: Continue with Google, Apple or Facebook, depending on where you are. Two names do not work: Instagram and X are not supported sign-up methods [S1].

What if the TikTok verification code never arrives?

Check the boring things first: wrong country code, a typo in the number or address, a full mailbox, a code sitting in spam. TikTok's own fix list for a missing phone code is three lines: select the correct country code, enter your phone number with the prefix "0" and without the country code, then restart your device and request a code again [S2].

Here is the part other guides fumble. Another TikTok page gives the same fix with the 0 included. Both versions come from TikTok. If one format fails, try the other.

Then stop requesting codes. Every new request replaces the old one, and an old code that arrives late will not work. The SMSOTPS FAQ states the same rule: use only the newest code, and after a waiting period shown on screen, request a fresh code once and enter it promptly and exactly as shown (https://smsotps.com/faq). For an email code, check for typos, look in spam, and confirm the mailbox is not full. If it still does not land, use a different inbox you control, or switch the sign-up to your phone number.

"This phone number is already registered"

That message means the number is linked to another TikTok account — a forgotten old account, or a recycled number your mobile network handed to someone before you.

TikTok shows you the profile picture of the account already linked to that number. If it is yours, tap Log in instead. If it is not yours, you can continue with the number — and know what that does: it removes the number from the other account, links it to your new one, and TikTok notifies the previous account [S3]. A deleted account stays deactivated for 30 days before it is erased permanently, and only after that can its number or email link to a new account [S2]. TikTok says it does not control number recycling, so if sign-up is blocked by someone else's old account, the cleanest move is signing up with your email instead.

The mistake that costs people their account

A one-time virtual number receives one code once. TikTok does not stop at one code. A new device, a password reset, a changed number — each of those sends a code to the registered number. A one-time number gets you in the door and locks you out of the house.

Match the number to the account. A throwaway account you will never log into again? A one-time activation does the job: choose the service and the country, check the price, get the number, paste it into the sign-up form, and request the code once SMSOTPS services. An account you plan to keep — your main TikTok, anything with followers, anything tied to your name? Use a number you control long-term and can access again, and add a recovery email at sign-up.

SMSOTPS says the same on its own FAQ: a short-term number should not be the only way back into an account you cannot afford to lose, and acceptance is decided by the service you are signing up to (https://smsotps.com/faq). Check the live price before you commit SMSOTPS pricing, or look at the shared inbox on the free-numbers page first SMSOTPS free numbers. For money rules — cost, active window, what happens when no code arrives — read the SMSOTPS FAQ and the live order page, not this article.

Getting back in: password reset and recovery

Logged in: Profile, Menu, Settings and privacy, Account, Password, then follow the instructions [S4]. Logged out: on the login screen tap Sign up, then Log in at the bottom, choose Use phone / email / username, pick Email / Username, tap Forgot password?, and choose to reset with your phone number or email [S4]. If you joined through another social account, reset the password on that platform instead — TikTok cannot do it for you [S4].

One error confuses everyone: "unrecognized device." It appears when 2-step verification is on and you try to reset a password from a device TikTok has never seen. The fix is a device you have used before. No trusted device left? Submit an account recovery request from the login screen: Forgot password?, then Recover account, then follow the steps to verify your identity — TikTok may ask for your registered email, phone number, or previous passwords [S4].

Two more routes exist for the worst case. If you cannot log in or reset your password, TikTok lets you recover the account by asking friends you are connected with on TikTok to verify you [S5]. If you lost access to the sign-up email entirely, the reset-authentication-method form — reached from the Need more help? button — lets you prove who you are and reset the method, a process that can take up to 30 days [S2].

Turn on 2-step verification before you need it

Go to Profile, Menu, Settings and privacy, Security & permissions, then 2-step verification, and choose at least two methods: Phone, Email, or an Authenticator app [S5]. Email plus an authenticator app is a complete setup with no phone at all. If you turn on phone 2-step verification later and then want to unlink the number, disable 2-step verification first — TikTok blocks the unlink while it is on [S2].

Change the number or email later

To change the number: Profile, Menu, Settings and privacy, Account, Account Information, Phone number, Change phone. Enter the new number, tap Send code, enter the code sent to the new device [S2]. The email path is the same, under Email, then Change email [S2]. One catch: both the old and the new contact must be active and verified, because TikTok sends codes to both [S2]. You cannot unlink a phone number or email if it is your only way in — add and verify the replacement first, then remove the old one [S2].
