Forgetting your credit card password will not affect your cancellation. You can log out after reporting the loss of your password. If the bound mobile phone is lost, you can cancel it after applying for a new mobile phone card. The specific cancellation process is as follows:

1. Most banks call credit card customer service to cancel the card over the phone. Very few banks can cancel the card at the counter. For example, Bank of China has two methods: telephone customer service and counter. Special card types of Shanghai Pudong Development Bank require cancellation at the counter.

2. In most cases, cardholders will not notice the arrearage caused by canceling the credit card until the bank sends a reminder notice and an overdue notice, which also results in a bad credit record. Canceling a card does not mean that we will never see each other again in this life. The disconnected friendship can still easily drag you down. Cardholders should pay attention to the following after canceling the card:

1. If the annual fee calculation period is not reached, the annual fee is waived. As for the standard of annual fee, when canceling, it is best to pay off the account balance and then deposit the excess payment of the corresponding annual fee, or "grasp" consumption to reach the free standard before canceling.

2. You should call the bank's credit card customer service center 45 days after canceling your credit card to confirm whether it has been canceled and whether there are any abnormalities in the account.

3. To ensure account security, the card must be with you when canceling the card over the phone.

4. Be sure to cut off the magnetic stripe after canceling the credit card. If the card is intact, it can still be used in some consumption places where only the card number is extracted without verifying the information, and it may be stolen.
