Using a password manager after identity theft

Identity theft and credential breach are related but different problems. A credential breach means specific username/password pairs have been exposed. Identity theft means someone is actively using personal information — your name, address, Social Security number, or payment card details — to open accounts, make purchases, or access existing accounts in your name. A password manager addresses one part of the recovery and prevention picture; it does not address all of it.

After identity theft, the credential hygiene question is real: an attacker who has successfully impersonated you may have also changed account passwords, linked new recovery email addresses, or established persistent access through methods a password manager reset won't immediately close. The password rotation is necessary but not sufficient.

Quick answer

You need ongoing monitoring for new account openings in your name

Dark web monitoring (Dashlane or Keeper BreachWatch) — alerts when your credentials appear in new breach datasets; not a substitute for credit monitoring

You want to secure all accounts with unique passwords immediately

Bitwarden — free, unlimited; the fastest path to unique credentials across all accounts

You want email alias protection to reduce future exposure surface

Proton Pass — SimpleLogin integration creates unique aliases per service, so future breaches on one service don't expose your primary email

When it matters

Enables rapid credential rotation — a password manager with vault health reports shows you which accounts share passwords, enabling systematic rotation starting with the highest-consequence ones
Provides unique credentials going forward — after identity theft, the motivation to finally stop reusing passwords is at a high. A password manager channels that motivation into a durable system
Supports dark web monitoring — ongoing monitoring alerts you when credentials appear in new breach datasets; reduces the lag between exposure and remediation
Email alias generation — creating unique email addresses for each service limits cross-service identity linkage for future accounts

When it fails

A password manager doesn't monitor credit or banking activity — identity theft often involves fraudulent accounts or charges that require credit monitoring, not credential monitoring
It doesn't remove your personal information from data broker databases — if your SSN, address, and date of birth are circulating, credential rotation doesn't address that exposure
It doesn't close compromised recovery paths — if an attacker added a recovery email or phone number to your accounts, changing the password doesn't remove their access via recovery

How providers fit

Bitwarden fits the immediate response phase — fast setup, free, broad import support, vault health reports on Premium that help prioritise which passwords to change first.

Dashlane fits the ongoing monitoring phase — dark web monitoring across 20 billion records provides early warning for future incidents, which matters more after you've already experienced one.

Proton Pass fits the reduce-future-exposure phase — SimpleLogin email aliases mean that future account openings use unique addresses; a breach on one service doesn't expose your primary identity.

Bottom line

A password manager is a necessary component of identity theft recovery, not the complete solution. Pair it with credit monitoring (separate service), review all account recovery paths for unwanted changes, and use the migration as an opportunity to establish email aliases for new accounts going forward.
