Start by deciding what you need to protect and from whom; then secure the accounts, devices, and communications that matter most to you.
Set realistic privacy goals before choosing tools
Effective security is about reducing specific risks, not trying to hide everything from everyone. The Electronic Frontier Foundation (EFF) recommends making a security plan before selecting tools. Ask yourself:
As an Amazon Associate I earn from qualifying purchases.
- What do I want to protect? Examples include email, location history, private messages, contacts, and files.
- Who might seek access? Consider the different capabilities of an account thief, someone with physical access to your device, a service provider, or a government agency.
- What would happen if the information were exposed? The consequences help determine how much protection is worthwhile.
- How likely is the threat, and what effort can I sustain? A setup you can use reliably is generally more useful than an elaborate one you cannot maintain.
EFF’s Your Security Plan page was last reviewed on October 27, 2023. Its central point remains useful: security depends on the person, the threat, and the consequences—not on one universally best tool.
Secure the accounts that could expose the most information
Turn on multifactor authentication
Enable multifactor authentication (MFA) on important accounts, starting with email. Email is often a route to reset passwords for other services, so losing control of it can expose more than the messages in that inbox. MFA adds an identity check beyond a password.

The Cybersecurity and Infrastructure Security Agency (CISA) recommends using the strongest MFA option an account supports. Where available and practical, a physical security key using FIDO2 can provide strong resistance to phishing. Check that the services you rely on support the key, and set up any recovery method the service provides. A security key helps verify account sign-ins; it does not encrypt files or prevent a provider from disclosing data it holds under applicable legal process.
Encrypt devices and keep recoverable backups
Protect data stored on devices and removable media
Use the built-in encryption available for computers and mobile devices that store sensitive information. Consider external drives, memory cards, and other removable storage too. CISA also advises encrypting files where appropriate. Encryption can make stored data harder to read if someone obtains the storage, but it is not a shield against every kind of access: it does not remove copies already uploaded to online services, and protection depends on the device’s state, configuration, and how keys are handled.
CISA’s device-storage guidance describes AES-128, AES-192, and AES-256 as highly secure for practical purposes, noting AES-128 may be easier on older or slower devices. That guidance is not a guarantee that any particular product or configuration is safe. Strong encryption still depends on sound setup and secure key handling.

Back up important files and protect recovery access
Keep backups on secure external storage or with a vetted cloud service, as CISA advises. Backups can help you recover from theft, damage, or device failure. Store recovery keys and backup credentials securely: losing them can make encrypted data inaccessible, while leaving them exposed can weaken the protection they are meant to support.
Use encrypted communications without confusing privacy with anonymity
Encryption can protect message content in some circumstances, but it does not necessarily conceal metadata—the information around a communication, such as who contacted whom, when, or how often. EFF’s Surveillance Self-Defense materials treat encryption and metadata as related but distinct issues. An “encrypted” label therefore does not mean that every detail about a conversation is hidden.
When choosing a communication tool, assess what it protects, what information it may still reveal, and whether the people you communicate with can use it safely. The available guidance establishes a way to evaluate those questions, not a current comparative ranking of messaging products.

Reduce unnecessary commercial data collection
Government surveillance and commercial data collection are connected privacy concerns, but they are not the same process or governed by the same rules. The Federal Trade Commission (FTC) described commercial surveillance in an August 11, 2022 rulemaking notice as the collection, analysis, and profiting from information about people. It identified potential harms including physical or economic injury, psychological harm, reputational injury, and unwanted intrusion.

Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Minimizing information you provide to services and reviewing available privacy settings can reduce some commercial exposure. The FTC notice asked questions about collection, use, retention, transfers, consent, and opt-outs; it should not be read as establishing one general consumer right to opt out of all data collection.
In an August 2025 statement, FTC Chairman Andrew N. Ferguson warned that weakening end-to-end encryption could expose people to surveillance and other harms. That was the chairman’s statement, not a blanket judicial ruling. He also noted that companies remain subject to the FTC Act’s limits on unfair or deceptive practices.

Understand that government access rules depend on the situation
The legal discussion here is U.S.-focused. It should not be applied automatically to other countries, or treated as one rule for law enforcement, intelligence collection, provider-held records, and searches of devices at the border.
The ACLU advocates Fourth Amendment warrant protections for certain phone records and direct tracking. That advocacy overview does not establish a universal rule for every government request. Applicable rules can depend on what information is sought, which government actor is seeking it, the legal authority invoked, and the circumstances. Phone-data and device-search rules are contested and context-dependent.
Border device searches are a separate concern
The ACLU describes legal uncertainty and litigation around searches of electronic devices at the U.S. border. If you face an actual border search, investigation, or subpoena, consult current legal counsel or an up-to-date rights guide. General privacy advice cannot determine your rights or obligations in an individual case.

Build a maintainable routine around your risks
Use your security plan to decide what to do first and what you can keep doing consistently. A practical starting point is to identify your most sensitive accounts, data, and communications; turn on the strongest supported MFA for key accounts; encrypt devices and storage that hold sensitive data; maintain secure backups; and choose communication tools based on both the content and metadata they protect. Revisit the plan when your devices, accounts, or circumstances change.
The aim is meaningful risk reduction—not a promise that the government, a service provider, or anyone else can never access information about you.
