Comparison at a glance

1. Safe onboarding step: Official app

Account-security onboarding should begin from the official domain or app and stay inside the authenticated security interface. The official app step concerns trusted Bybit mobile installation. Confirm the current control in the user's own account, then verify publisher and update status. Never copy a password, one-time code, biometric, recovery phrase, private key, API secret, or identity document into notes or chat.

Design for loss before changing the primary method. A passkey may depend on one device, a platform keychain, a password manager, a hardware key, or a synchronized credential provider. The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device regional listing. Keep the existing method until the independent backup has been tested from a trusted context.

For official app, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Verify publisher and update status, then sign out of a non-critical session and prove the alternate path. If regional listing remains unresolved, stop before deleting any working authenticator.

2. Safe onboarding step: Account eligibility

The account eligibility step concerns identity and feature availability. Confirm the current control in the user's own account, then check the authenticated account.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device entity-specific access.

For account eligibility, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Check the authenticated account, then sign out of a non-critical session and prove the alternate path. If entity-specific access remains unresolved, stop before deleting any working authenticator.

3. Safe onboarding step: Prerequisites

The prerequisites step concerns passkey or SMS plus email or TOTP. Confirm the current control in the user's own account, then confirm independent factors.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device account variation.

For prerequisites, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Confirm independent factors, then sign out of a non-critical session and prove the alternate path. If account variation remains unresolved, stop before deleting any working authenticator.

4. Safe onboarding step: Primary device

The primary device step concerns phone trusted for approvals. Confirm the current control in the user's own account, then assign one controlled device.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device device replacement.

For primary device, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Assign one controlled device, then sign out of a non-critical session and prove the alternate path. If device replacement remains unresolved, stop before deleting any working authenticator.

5. Safe onboarding step: Secondary request

The secondary request step concerns website or another device initiation. Confirm the current control in the user's own account, then identify the originating session.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device session compromise.

For secondary request, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Identify the originating session, then sign out of a non-critical session and prove the alternate path. If session compromise remains unresolved, stop before deleting any working authenticator.

6. Safe onboarding step: Transaction details

The transaction details step concerns asset, network, address and amount. Confirm the current control in the user's own account, then compare every field.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device display truncation.

For transaction details, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Compare every field, then sign out of a non-critical session and prove the alternate path. If display truncation remains unresolved, stop before deleting any working authenticator.

7. Safe onboarding step: Approval

The approval step concerns explicit primary-device confirmation. Confirm the current control in the user's own account, then approve only recognized requests.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device notification delay.

For approval, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Approve only recognized requests, then sign out of a non-critical session and prove the alternate path. If notification delay remains unresolved, stop before deleting any working authenticator.

8. Safe onboarding step: Rejection

The rejection step concerns unknown or incorrect request. Confirm the current control in the user's own account, then reject and secure the account.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device existing compromise.

For rejection, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Reject and secure the account, then sign out of a non-critical session and prove the alternate path. If existing compromise remains unresolved, stop before deleting any working authenticator.

9. Safe onboarding step: History

The history step concerns past approvals and outcomes. Confirm the current control in the user's own account, then review non-secret evidence.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device retention period.

For history, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Review non-secret evidence, then sign out of a non-critical session and prove the alternate path. If retention period remains unresolved, stop before deleting any working authenticator.

10. Safe onboarding step: Recovery

The recovery step concerns lost primary device or feature removal. Confirm the current control in the user's own account, then test the official recovery path.

The venue's public documentation can describe supported paths, but it cannot prove the state of this account or device cooldown and support.

For recovery, record only non-secret evidence: method label, custody owner, setup date, tested device and recovery owner. Test the official recovery path, then sign out of a non-critical session and prove the alternate path. If cooldown and support remains unresolved, stop before deleting any working authenticator.

Decision scenarios

Scenario 1: when official app becomes decisive

Consider a reader whose main constraint is trusted Bybit mobile installation. The correct response is not to infer a universal platform or product winner. It is to verify publisher and update status, retain the evidence, and define a stop condition before funds or permissions are committed. If the evidence changes, the decision must be reopened. This produces a repeatable operating rule rather than a one-time opinion.

Scenario 2: when account eligibility becomes decisive

Consider a reader whose main constraint is identity and feature availability. It is to check the authenticated account, retain the evidence, and define a stop condition before funds or permissions are committed.

Scenario 3: when prerequisites becomes decisive

Consider a reader whose main constraint is passkey or SMS plus email or TOTP. It is to confirm independent factors, retain the evidence, and define a stop condition before funds or permissions are committed.

Scenario 4: when primary device becomes decisive

Consider a reader whose main constraint is phone trusted for approvals. It is to assign one controlled device, retain the evidence, and define a stop condition before funds or permissions are committed.

Scenario 5: when secondary request becomes decisive

Consider a reader whose main constraint is website or another device initiation. It is to identify the originating session, retain the evidence, and define a stop condition before funds or permissions are committed.

Scenario 6: when transaction details becomes decisive

Consider a reader whose main constraint is asset, network, address and amount. It is to compare every field, retain the evidence, and define a stop condition before funds or permissions are committed.
