6 minute WhatsApp guide
What information is needed for a WhatsApp investigation?
A useful first review does not need your password or verification code. It needs a clear goal, short timeline, device map, account status, and the sources you still control.
The short answer
For a WhatsApp investigation, prepare the phone model, WhatsApp number with country code, current access state, important dates, linked-device screenshots, backup date and cloud account type, previous phones, connected email and mobile-number status, suspicious messages or alerts, recovery steps already tried, and the exact result you want. Do not send live verification codes, PINs, backup passwords, encryption keys, or complete device images in the first enquiry.
Start with one clear question
State the result in one sentence: regain my WhatsApp account, find out whether another device accessed it, recover one deleted conversation, restore missing media, explain messages I did not send, review a repeated takeover, or assess a WhatsApp Business incident. A clear question determines which devices, accounts, dates, and records matter most.
Add the priority and date range. A case involving one deleted chat from last week differs from a year of suspicious access across several phones. If several outcomes matter, rank them. For example: stop current access first, preserve changed messages second, recover customer chats third, and review the phone after the account is stable.
Create a short account and incident timeline
Record the last time WhatsApp worked normally, the first unexpected event, verification prompts, sign-outs, linked devices, profile changes, messages contacts reported, deleted chats, mobile-service problems, phone changes, backups, and every recovery attempt. Approximate dates and times are useful. Preserve original notifications and screenshots instead of rewriting their wording from memory.
Include what happened immediately before the problem: a phone repair, device transfer, SIM change, suspicious link, support call, shared code, new computer, application install, account email change, or physical access to the handset. This context often explains why several events that look separate actually belong to the same access route.
Map the phones, computers, accounts, and backups
List the current phone, previous phone, tablets, linked computers, browser sessions, and any other device that used WhatsApp. Include the make and model, operating system if known, who uses each device, current access, and whether it still displays relevant messages. Do not wipe an old phone or log out a useful session before its contents are considered.
Record the mobile provider, number status, connected email, Apple or Google Account, backup date and size, cloud storage, computer backups, and whether end-to-end encrypted backup was enabled. For WhatsApp Business, add staff access, companion devices, customer reports, business profile changes, catalogue activity, and the business systems connected to the number.
Preserve the useful evidence without oversharing
Useful first-review material can include screenshots of Linked Devices, registration or two-step prompts, unfamiliar messages, profile changes, account alerts, carrier notices, contact reports, and backup settings. Keep the original files where possible so dates and context remain available. Cover unrelated private content before sending an example if it is not needed to explain the case.
Do not include live SMS codes, two-step PINs, passwords, passkeys, backup passwords, 64-digit keys, recovery phrases, full account exports, or complete phone backups in the first form. TechForensiq will explain the secure transfer method and exact data needed after the case is scoped. The first message is for triage, not a full collection.
What you receive after the case review
The review matches the problem to the right engagement: account recovery, linked-device investigation, deleted-message assessment, backup analysis, phone security review, mobile forensics, business account recovery, or a combination. You receive the proposed objective, sources to be checked, information or devices needed, expected deliverables, timing, and price.
Good preparation shortens the first exchange and makes the quote more accurate. It also prevents a high-value device or backup from being overlooked. If you do not know every answer, send what you have. The essential starting points are the desired outcome, phone type, account status, short timeline, available devices, backup information, and what you have already tried.
