Recover Telegram 2FA-Locked Account

My personal Telegram account is currently locked because the two-step verification password I set is being rejected. I still control the phone number linked to the account and can receive SMS or calls on it, but I’m not sure whether I ever added a recovery email.

I need a specialist who already knows the ins-and-outs of Telegram’s support and appeal process to help me regain full access without deleting the account or losing my chat history. The task ends successfully when I can log in again from both desktop and mobile, with two-factor authentication properly reset and future recovery options configured.

Please outline briefly how you plan to approach Telegram support, any documentation you will require from me, and the expected timeline for resolution.
